I'm having a problem installing the AI enhancements portion of BP. As much as I enjoy a more challenging game, I wouldn't mind so much if I can skip that and still play TDD, SoS, TS, etc. together. So, if I don't install the AI enhancements, can I still play them together? Here's the error I get, if any of you know how to fix it:

[./override/CEFGT02.CRE] loaded, 1484 bytes
ERROR: [CEFGT02.CRE] -> [override] Patching Failed (COPY) (Invalid_argument("String.sub"))
Stopping installation because of error.


EDIT: When I open up the game it says" (i'm paraphrasing here, of course)play bg1 with totsc or bg2 with the new expansions: Tortured Souls, Shadows over Soubar, Check the Bodies, and The Darkest Day"
Does this mean that I have BP installed? Also, I installed Region of Terror. Is that supposed to show up in the expansion list also?

Thanks in advance for any responses.
