error running mta

[Guest]

my system:

PIII ~1ghz

384mb ram

nvidia geforce2 mx400 64mb

microsoft windows xp sp2

when trying to run mta, i get the following error message:

"Multi Theft Auto 0.5 has encountered a problem and needs to close. We are sorry for the inconvenience.

If you were in the middle of something, the information you were working on might be lost."

this error message has two buttons: debug and close

when i press debug, my microsoft visual studio opens up and it gives me this message "Unhandled exception in APP01.exe: 0xC0000005: Access violation" and a disassembly window in background with this:

"

-> 7C901230 int 3

7C901231 ret

7C901232 mov edi,edi

"

i press ok and then in disassembly window:

"

00405BC0 mov edi,esi

00405BC2 xor eax,eax

-> 00405BC4 repne scas byte ptr [edi]

00405BC6 not ecx

00405BC8 dec ecx

"

i don't imagine what could be wrong.

thanks for any info
