I checked it's a known issue, but is there any solution for this?

Re: BB Desktop crashes all the time

Hi - where is this documented as a known issue (I get the exact same EventType but different details otherwise)? I've been having this trouble since upgrading to the since-discredited version 7, then attempting to downgrade back to 6.1 (although the P2 field seems to indicate that my machine still thinks it's running version 7).

Re: BB Desktop crashes all the time

Guys read this post! It worked for me! you have to clean registry and make reboots if you want to roll back to 6,1 because of some registry keys!
