Loosing CAT ports nr after reboot


Since a couple off week, after installing the latest version of smartsdr, I am loosing the device nr for the cat ports.

Checking with CommNameArbiterTool, the ports are present but no Kernel name and therefore not recognized by my programs like Logger32 JTDX etc.

I have to remove the ports from CATSDR close CAT and start again to create the ports.

Is this a known problem?

    Mike - Do they have a work around or are they just collecting numbers?

    They have a procedure to resolve it.

    Sometimes, it is a 100% windows issue causing it. I had 1 friend who had it and reinstalled Windows and the problem disappeared.

    I found the problem, there was another vsp manager loaded.

    I did remove the flex vsp manager and the other one.

    Restarted windows.

    Did a new installation of the flex vsp in the proper C:\applications directory.

    Restarted windows and everything works ok now.

    Restarting windows between processes is needed to clean the windows stacks

    Thanks for your help

    One rule of good operation:

    ALWAYS close CAT before restarting your computer, and ESPECIALLY before allowing Windows to auto-reboot the computer after Windows Updates.

    Sometimes Windows Update's "auto-reboot" does not do so "gracefully."
