Folks need more info to solve your problem.
Odd are your subscribed to an out of date Mod, which needs to be un-subscribed, and the local copy deleted

i agree that it would be help in solving this issue by giving more information, sadly this and the tiny log below who isnt helping either is all i can say about this problem.
there are no error messages, only a tiny window with the above mentioned text.
un-subscribtion of all mods didnt help.

Delete the Natural Selection 2 folder in
Users\USERNAME\AppData\Roaming

This should force default Settings.

the only thing in said folder is the log i already posted, deleting the whole folder didnt change the error or contents of the logfile.
