I just purchased a license for ME2 and wouldn't you know it, it crashes after posting a new entry. The entry will post and I get the growl notification. Then ME disappears and I get the OS X "app quit unexpectedly" box.
It happens every time now. Before entering the registration info, I was able to publish a couple of test entries with no problems.
I messed around with the perfect preview, but other than that it's a stock install.
Here's the error log if I hit the "Report..." button on the app quit unexpectedly box.
I wouldn't be surprised if I messed something up somewhere.
