[Gabbdez]

So I just baught this game for the Persistant Fronteir mod and I did the usual thing downloading it and putting the mod file in the modules file. Then i launched the game and all the logos show up but then when it starts to load it crashes and says

RGL ERROR unable to open file CommonRes\wb_mp_objects_a.brf

So what am I doing wrong?

If someone knows how to fix this please tell me.
