Yep, I knew the patch would be around that size but my download & install box says I have 110gigs to d/l ! tried all the above advice, even did a system restore. I think like others, i will ask for a refund & come back later when some of the major bugs are fixed. I don't hold out much hope for the refund as it did work originally & its been a few weeks since I purchased it. "C'est la Vie". Cheers folks
