you know, you could probably have trimmed some of that. to be honest nobody here can interpret most of that garble anyway.
however, i can suggest a workaround for this problem, which occured to my when i switch to using backup-cds (the BG2 discs are low-quality and tend to die if overused).
go to
www.gamecopyworld.com . dont be scared by the legalities of it, your just here to run a game you legally own. (you do legally own it dont you?)
find a mirror (just hit a random one in the right area, but any should work)find a no-cd patch for the correct verion of BG2. the site is fairly simple to follow. last time i was there BG2:ToB was in the new games panel in the centre of the main page. theres a complete game index somwhere to the right. while your there, you should also get any other no-cds that will make your life easier, and your discs safer, jsut in case somebody decides to snap them. (happend to me).
just gone through your post again, there are _no_ problems that i can detect. id say it was a dead CD. a CD-R might have better luck reading it than a standard CD-ROM, since they have to have tighter focussing etc. but its simpler to get a no-cd patch.
