well, after trying re-installing and deleting all files - I tried something else to get rid of my "[ScriptManager] Duplicate class "Cu_veh_t34_85_44ModelSkin" definition." problem.
I manually opened regedit and did a "find" for everything with t34, lighthouse, and tiger... and deleted every entry I could find.
After rebooting just to be sure I installed the game, then the christmas release and now we are once again back in action.
I havnt tried the mission 6 fix yet, because i'm still not sure if it can be used with teh xmas release... but I'll try it when I get there again.
I did run into a glitch in mission one though. I killed/knocked out all the enemies and the 3rd objective of knocking out the "hidden" t34 wouldnt trigger... (behind house
) I dont know why, but I got stuck in the level unable to "finish" even though he was certainly dead.
Its only happened once, but nonetheless I thought I'd mention it.
