Like the other posts stated, the Models.big file may be the culprit in your issue and what type of rig you are using. The weird thing is that in my case, my toshiba laptop with Win 7 64-bit can play the MVP14 mod with no issues. Even with the default Models.big file at 819mb. But when i try to play the mod on my Dell Desktop Win 7 64-bit, the bar will bar will go half way and the game will crash to the desktop. Now when i did some modifications to the Models.big file and reduced it to approx 660mb, the game is working flawless on my Dell Desktop now. Also if you look at other mods, the Models.big file is not that big. I believe in MVP08, the Models.big is about 572mb which is the biggest i've seen prior to MVP 12. MVP 12; MVP 13; and MVP 14 Models.big file are in the 700mb plus range. For some odd reason, my Dell Desktop can't handle it and the game will crash to the desktop. Once i did some deletions in the Models.big and broke it down to about 660mb, the game is running with no issues. IMO it all depends on what type of rig that you are running and if it can handle the size of the Models.big file. Also break the Models.big file down to about 660mb and see what happens. Great Mod!!! Keep up the good work.
