ok now that i have your specs we can narrow things down until we find the problem. i know my brother had a similar problem with the download version and found that once he installed it he had the same problem as yourself and we fixed it by unistalling the game and then deleting the root folder manually and then reinstalled it and away it went but i suspect that the dvd version has been corrupted in some way during the install also i would check that if it has the patch pre intstalled then the patch may be cause but i need one of the moderatorson here to first confirm if the dvd verion was pre patched as if not there may a differnt patch for you to install but give advice a try and it might just work .

good luck and if all else fails we can try something else
