Cannot play ofp campaign after installing patches

[elfranko 0]

Hi all - having a massive problem - I've got the original version of FP; to which I added the Gold upgrade and the Resistance addon. Then I patched FP to the eyeballs with all the right patches. But I didn't patch Resistance. I have been playing the OfP campaign for a while now and it was going great. Then I joined a clan and they play using Resistance multiplay; so I patched up Resistance and also installed the Resistance Beta patches. Now when I click on Campaign in FP, the game crashes to the desktop - MP and editor both work in FP and so does Res. But as soon as I click Campaign; the game bombs out. What gives??

My Pc is an AMD 2800; 512mb ram; the game is on an 80gb hdd and a secondary scratch disk is set up on my d: 160gb; I have a Ti4200 128 NVidia card patches up and I have the latest Mobo drivers as 1942 wouldn't play without them. So what's up? Also it's a winXP machine.

Everything worked until the patches for Res were added. I don't know if it was the beta ones that did the damage or the 1.91 one - I think I am 1.96Beta on Res. I think I have the two Red hammer and OfP campaign mini patches that came out for patch 1.91 installed - if I try to run them now, they report an "error in the patch itself; corrupt upon download may be" it says. This only occurs if you have already got the patch istalled from experience.

Any help would be great!

thanks
