I am in the same boat. I am using an AJA t-tap however it is not the issue because not using it still wreaks havoc on my project. Constant freezing and crashing. Even Filmimpact transitions causing issues. I fixed the permissions folder issue that apparently was a culprit – only difference now, after a crash it pops up the dialogue box to send comments to Adobe wasn’t doing that before. Still full of issues.
What a disappointment. I specifically upgraded (own CS6) to get the offset sync feature to use with AJA T-Tap but still not getting the full use of software, constantly having to restart. And this is a 3 minute video!
