JT65 Problem with 1.4.11

I just installed the latest SmartSDR software (1.4.11) and I'm experiencing a strange phenomenon.  With either WSJT-X or JT65-HF I see the signals FB on my screen, but I can only decode very strong signals (-1 db).  All other signals, though they look good on the screen, won't decode.  At first when I was using WSJT-X, I thought that this problem was software related.  However, now that I've experienced the exact same issue with JF65-HF, I suspect that it is either a setup problem or some sort of a bug.  All the parameters are setup basically the same way I have done them before, so I'm a little mystified as to what may be going wrong.  Any ideas about where I should look first?   Tnxs & 73 de Carl, N8VZ

Carl,
   I am thinking that it might be DAX related and that rebooting the PC might solve the problem..

OK, Al, that is worth a try.  I'll do it and let you know.

I noticed this with wsjt-x and my 6500 on 1.4.11 if I had the slice bandwidth set super wide.

OK, I solved the problem.  It was a clock sync issue.  When I checked in Services the Dimension4 service was stopped.  I could not start it manually.  So, I uninstalled the program and installed Meinberg NTP instead.  Once it did a clock sync, I started to decode signals.  Thanks for all who answered my query.  I appreciate the help. 73 de Carl, N8VZ

Update: Had some problems with Meinberg NTP, so I uninstalled it and installed Time-Sync instead.  It also installs a service, which is working great: http://www.speed-soft.de/software/time_sync/details/download.php?language=en

check to see that W32TIME is running in services tab of Task Manager

Also schedule a task W3TM/resync every so often
