Please, anyone can send me the data6.cab file of ToB CD???
I really need this file, mine is bugged.

There is no data6.cab file on the ToB CD. Plus you can't bug a CD file.

I did not bugged, but here is what heppened:
I live in Brasil and here there is not the Expansion Set and it will never come. I have the original BG2: Shadows of Amn and I love it, as I play AD&D since I was 12 years old. The thing is that a friend of mine lives in New York and he sent me the original CD of the Throne of Bhaal, but I don't know what happens when I try to install it...it asks for a data6.cab (after askig for 3,4 and 5 either, but these ones are in CDs 2,3 and 4 of the SoA), so i deduced that the data6 would be in the Expansion Set CD, but it's not, and as you told me now it's really not.
Can anyone help me please???

You know, I had something like this happen to me once. I am probably wrong but it seems to be connected the registry entries for SOA being messed up. I had to uninstall all of Baldurs Gate, making sure all mention to it was removed from the registry (using regedit.exe). I also ran Norton utilities to correct errors. Then I re-installed SOA, installed the SOA patch, and then ToB installed just fine. This worked for me.

Crap, I did what you said and now when I try to install my Shadows of Amn it asks for a CD5, and this has never happened before (I have the game for 3 years).
No idea of how to fix it. Any help?
Thanks

the cd5 bug is a known bug, quit the installer, and start over, it should fix itself after that, or get the patch from bioware, I think there is a patch to deal with the cd 5 bug.

I had the same problem but my happend, when I switched from a Cd-rom to a cd-rom/burner. I had to install my other cd-rom to get it to install. But sounds like deverece solved your problem. At least know I know how to solve this problem as well.
