Only one problem with all of those possible errors - the game played before under the same configuration with no problems. In fact it played brilliantly. Then I did a reformat - swopped drives and upgraded to a 40GB drive from a 20GB both WD, both Caviar, now I can't get it to play at all without this confounded error - I did post on this board about 8 months ago but can't find my original posting?????? so I created this new one in the hopes that someone had found a possible workaround.As for a file corruption, I guess that is possible, even though I am installing from the original cds?
