[2.13Pro] Crash on load
 
I had just run CMUD, the loading screen was saying "Initializing sessions...", when it crashed.
I chose close app, then ran it immediately after a heap of times, including multiple instances, but couldn't reproduce the crash.
I've run this version successfully on my database a couple of times already, and the database should have been mostly the same for this run (apart from some variables changing).

Edit:
It happened again, and I'm suspecting bad interaction with something else accessing the files... possibly Vista's search indexer or my antivirus (BitDefender).

What I did:
Had a backup of CMUD's database directory (which is within my home directory) called "CMUD - Copy"
Deleted the original directory (called "CMUD").
Renamed the copy back to the original.
Ran CMUD.
I think moving things around is likely to trigger these background file readers (I can hear my harddisk going after doing that), and I did it quite fast, so they might have still had the files open when CMUD started up.

Unfortunately, I still can't reproduce it again, using these steps

Looks like you're hitting an error when another process is still updating one of the CMUD dbs when you are trying to start up. I've seen this once or twice my self, but haven't been able to reliably reproduce it. the worst part is I forgot to take a copy of the bug report.
