NVM i found out that in the customer support it said to delete the .xft and config folder of Bitraider and not the full folder.....just found a thread that says to delete the whole bitraider folder and now it works ^^

Hello I am encountering a Launcher problem where my application after Logging in wont start. I am currently playing in the ST mode and already have tried all the options on the customer support site.....even deleted the .xft and config folder but the game still wont start. I am making it past the log-in screen but then the play button is greyed and it says i quote: "This application has encountered an unspecified error. Please try this patch again." I have tried to call customer support here in germany but it has been shut down. Any suggestions?
