Well, now I really screwed up. I updated to 0.92.99.7-testing, old database was deleted, and now armory keeps crashing as soon as it starts building databases, I tried like 6 times 
Can you try the final 0.93 release? A last-minute bug that primarily (but not exclusively) affected OSX was patched this afternoon. I'm reasonably certain it'll stop your crashes. If it doesn't, file a support ticket and send us traces and logs ASAP.
Thanks!
