Try renaming FolderViews.db from Settings folder to something else so OC can't find it
(if running ClickOnce version it is in C:\Users\YOURNAME\OneCommander)
and try starting it again. If it still crashes, try renaming one of the other files in there (it will force it to be regenerated). If you find a file that was causing the crash, you can rename back the other if you had settings changed, and please send me the renamed faulty file that was causing the issue it doesn't have sensitive information (support at programname dot com).
If program hangs instead of crashing you will need to terminate it in Task manager between renames.
I have found one issue in this version that could have caused program to crash, so other way would be to wait until I push the update in about 5 hours after this message.
