Unable to load game

Every time I execute the launcher, it updates the game files. But for some reason I’m getting this error “Unable to launch D:\Hellgate London\MP_x64\London2038_dx9_x64.exe” I had the same issue last night, I had to use both DX9 then later on DX10 due to this error appearing.

I decided to try and reinstall the game, which didn’t work as the setup file for some reason was trying to find files in the games installed location. Anyone got any idea what’s causing this error?
