Sonar PLat hangs/spins/does nada on startup

Lately (since the last two updates) I cannot get Sonar to launch EXCEPT by manually going into C:\Program Files|Cakewalk\Plat\Sonarplt.exe and double clicking the executable...

I've stopped using my Siatek Cyborg keyboard quick button to launch it, the shortcuts have been deleted and reset and then deleted again...

I have tried starting in Safe mode to make sure no plug-ins were hanging it...so far none of this works...

If I get it open and then shut it down and restart it it seems fine it's just the initial start up sequence is buggy right now...advice appreciated...
