TypeError on launching DCS

[stoop]

I get this error on launching DCS MTnull

Delete your Saved Games\DCS\launcher.sqlite3 file and start DCS again.

You should also just start DCS using the standard shortcut (or the DCS.exe file in the bin directory not bin-mt if you have your own shortcut or using directly). DCS is completely multithreaded now, they are both identical, and bin-mt and shortcut will be removed in the future.
