Before bringing about my unfortunate situation, I would like to say that I am extremely excited to play this game. Installation was fine, then I ran it, had a problem with the MSS DLL(miles error), fixed that(inserted the mss32.dll into the source sdk folder), then ran it again, it showed the main picture and then automatically closed due to a HL2.exe error. This is what I got from the event viewer: "Faulting application hl2.exe, version 0.0.0.0, time stamp 0x4445c334, faulting module scenefilecache.dll, version 0.0.0.0, time stamp 0x4474ce19, exception code 0xc0000005, fault offset 0x00003e2c, process id 0x11e8, application start time 0x01c8346d80811542." Any ideas? Thx =) edit: Btw, I also put the fixed HL2.exe file in the source sdk to replace the original...and still...no cigar.
