One suggestion I have is to download a copy of a freeware home edition program called TeraCopy for each computer you plan on playing the game on. It is light years faster than the default crappy Microsoft copying program thingy. It will make copying much faster. In fact I'm feeling so generous today, I think I'll leave a link for it
here. Major Geeks dot com is a fabulous one stop freeware/shareware programs bonanza...Plus they have excellent volunteer techies if your baby (computer, not human) has fallen on hard times. It is a must have site for your bookmarks. Cheers.
EDIT: Must. Read. OPs. Better. Missed the part about the whole league thing. Where's the D'oh smilie when I need it. Oh well this will have to do.

Sorry about that chief. That said the comments about the Major Geeks website stand.
