I thought 1.91 would include the previous 1.90 so I went from a fresh install of GOTY edition to 1.91. Now I'm getting bad frameeate/slow downs which were never a problem before. Was I right not to do 1.90 > 1.91 or have I messed up? What can I do to fix this if I messed up (preferably without reinstalling as it takes an age!

ok i looked in the root directory of OFP and no file there as far as i can see with a .rpt extension. System is AMD Athlon 1300, 256 megs memory, GeForce 2 32meg graphics and AC97 sound card. Until now the only problem I have had is the occasional loss of sound on OFP - I think its the sound card that does this but I've never found a solution other than its my hardware and i should replace the sound card. Restarting the game solves the sound loss, and it only happens occasionally. Yeah, I've got user mods. Vietnam Pack 2 and a couple of minor ones I think - they are all in Res folder if i remember correctly. i was thinking of reinstalling but keeping copies of my status files from Users...

I've got Operation Flashpoint GOTY edition. I'm on the mission where you are part of an amphibious assault on Malden and the game has mysteriously started crashing to desktop when I choose Campaign Game to continue playing. Single Missions works fine - I think there may be a corrupt save file or something. Can anyone help?
