edited May 2018 in SmartSDR for Windows
I came into the shack to find my computer in an apparent restart lockup.

Did a manual restart and got the "Windows has encountered a problem but we are fixing it and will restart when done" message. The progress window hit 100% and just sat there. Waited a long time (5min) and finally hit the power button and just did a power off/on restart.

All appeared normal until I opened SmartCAT and found I had gone from 8 or 10 setups to 2.

Not good. Uninstalled SMARTSDR, rebooted, reloaded SMARTSDR, still no joy.

Checked the Device Manager and all of my COM ports still appear there and say they are still assigned to FLEXRADIO but they don't show up in SMARTCAT. 

Is there a backup copy of the stuff from SmartCAT that is someplace I can bring back into operation?
In the past when I uninstalled SmartSDR and installed the latest version everything returned to normal. This has me scratching my head. Any ideas?
Thanks in advance.  Mike K7DD

    Try opening the cat program, then at the bottom of the panel right click on remove button and reset VSP ports

    Here is what happened.  When you PC crashed, it corrupted the XML file that SmartCAT uses to define the port parameters it uses because it was not allowed to close gracefully.  The CAT ports you defined previously that are no longer shown in the CAT windows have for all intents an purposes have been lost.  When CAT restarted, it detected corrupted XML settings file a created a new default one with one CAT type port that uses a COM port and one that uses a TCP socket.

    You have two choices.

    Option 1 - reset you FlexVSP ports so that the ones you see in Device Manager that are not associated with the ports shown in the CAT display (called "orphaned ports") are deleted and then recreate your CAT ports.  This is easy to do.  Open SmartSDR CAT, place your mouse cursor over the REMOVE button and select the menu option Reset FlexVSP ports.  Now recreate your com ports.

    Option 2 - you can open a HelpDesk support ticket and we can try to reassociate the FlexVSP ports that are orphaned in Device Manager with SmartSDR CAT by manually editing the CAT settings file.  This is not a complete recovery as if you had the ports associated with different slices or had set the CAT port parameter to something other than the defaults, we will not be able to recover those settings.

    Really your best bet is Option 1.

    The CAT settings file is located in %APPDATA%FlexRadio SystemsCAT.settings

    Doing that will mess up the FlexVSP com ports because it will not remove the associated registry entries properly.  You need to use the CAT application to create and delete the FlexVSP ports.

    OK. Well I was not the one who originally setup my system so I had software that was working with DDUTIL, CW Skimmer, FLDIGI, HRD, etc and now don't know exactly how it was setup. I DO have another computer (laptop) that was used with the rig for Field Day and it still has most of the original items still shown. Is there a way to locate the XML file and just copy it to a thumb drive and put it in the desktop PC?
    Is there a way to create a backup of the setup so I don't do this again?

    Oh, wow, if you are using a lot of different software but not knowing how it was set up, your best bet would be to sit down with your buddy and go through it all again. Take copious notes as well. If your system restore is bollixed, and it sounds like it is, after it is running again, make an image or clone of your hard drive, maybe with one of these:  https://windowsreport.com/clone-windows-10/   Windows 10 is experiencing some real issues right now, and having a drive with a clone image can save you a lot of grief.

    Yes, make a backup of the CAT.settings file I reference above.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
