Question: Where exactly is Armory building its database now?
According to the log file: C:\Users\Andreas\AppData\Roaming\Armory\databases
As for why it is stopping... It's possible, as Carlton suggested, there is not enough Disk space (it does mention 0GB space on BTC drive in the log??!?)... Or it might be that ArmoryDB is encountering an error.
Check dbLog.txt and/or post the contents
