I believe its UT2k4 causing the problem because I get the same message with frag ops and red orchestra, I have their newest releases plus both patches from ut2k4, I also redownloaded directx 9c, and even after awhile reinstalled all files. i got the error, cant find pandorasuch and such intro but after fixing this i get this new harder message:
