Okay,so I used to play LU ( Liberty Unleashed) mod for GTA 3,which is a MP mod.I haven't encountered any problems then.But from now on it keeps crashing and I don't know why.It's a crash in all servers when the chat says "Connecting to server IP......",it freezes.Here's the crash report:

Here are my system specs:
Xp Sweet 6.2 Final
TeChNi-AmEcO
Intel®
Celeron® CPU 2.80GHz
2.81 GHz,512 Mo of RAM
My system specs are apperently above the requirements,I recently installed a mod which changes the menu appearance and load screen appearance too,but It has no effects as I usually play with this mod in both Solo and Multiplayer GTA 3 normally.

I dunno why this happened,I reinstalled the game like 3 times..
Thank you in advance
