Well, at least I guess my AOM version is 0.5.1.219, because there is not a single hint which version I have when the program is running (hint: Make a version popup box under help), but the file version reports it back as that, so I guess it's te right version number.
Randomly happens when I want to access the Mylist tab. Sorry, can't edit posts as guest and I don't see the necessity to register here. Reach me on ar or ircif you need more feedback.
You can right click on the exe and select properties to get it's current version.
About the bug, the access violations are kinda hard to trace and won't occur in the same way in 0.6 anyway so not gonna dig deep into them.
Regarding the second error it's known and caused by a component I use, it's one of those "should not happen" errors and I'll just trap it in 0.6 so it'll go away.
