IWD Assertion 1338 Problem Options

[kix]

I recently decided to try IWD after having played BG, and I'm wondering if there's someone who could help with this assertion problem.

First, what I have:
Win98se
Gateway500
PentiumIII® processor
128mb ram
ATI rage128
SB audioPCI
Dx9 [did not install dx7 that came with game]

What I installed:
IWD
Official Patch [iwdpatch106.exe]
xpt remover [IWD_XPCAP.zip]
G3 Tweakpack [DaleTweak-v4.exe]
DaleKeeper

What happens:
The IWD screen appears, I click 'new game', create a character and when I press 'Done' it crashes to desktop with the following error:

Assertion Failed in CGameEffect.cpp in line#1388

I've tried creating multiple characters with the same result. Is this a tweakpack problem?

The interplay site was no help, and I'm pretty lost at this point.

Thanks for any help you can offer

P.S.
According to my Directx info in 'system info'; directx has no errors and tests fine.
