After working with CW Tech Support, I'm still having the same issues with the Command Center (CC).
Tried everything from the above suggestions and with Tech Support, including reinstalling the Platinum installation app manually from CW. First one that I had downloaded was found to be corrupted and unusable. Launched the manual installer by bypassing the CC, and installed Sonar Platinum. Now, it opens and I'm able to use.
Now, the only problem is, any updates are run thru the CC, which continues to crash during attempted use.
CW Tech said this is the first time he's seen this happening.
