Forum:Fallout 1 (modded, patched) crashes in RadScorpion cave

I installed Fallout 1 with the following patches and mods: (1) v.1.2.1 patch (semi-official). (2) v.1.3.5 patch by TeamX (unofficial). (3) high resolution patch Ver 2.2b. (4) NPC Mod by TeamX v3.5 (enabling NPC to raise level). (5) Fallout restoration project mod (enabling quests and NPCs that are omitted before the game's official release).

So I created my character, killed all the rats in the cave, and proceeded to Shady Sands. I then accepted the RadScorpion quest.

But whenever I go to the RadScorpion cave, the game crashes with the following Application Error: ''The exception Breakpoint A breakpoint has been reached. (0x80000003) occurred in the application at location 0x7c90120e''

''Click on OK to terminate the program Click on CANCEL to debut the program''

What happened? Which patch and/or mod is the most likely culprit? I think the high resolution patch is not the cause, because I uninstalled the hi-res patch, and the error remains (the hi-res patch is easy to install/uninstall with a click on the .exe, without having to reinstall the game from scratch). Anyone has ever experienced this before?

My system is the following: MSi Wind U100 netbook Intel Atom N270 1.6 GHz 2GB of RAM Windows XP Home Edition Service Pack 3

Thanks,
