gpxpatch problem!!!

I use gpxpatch 3.80. I've had it for weeks, but suddenly, when I try to run the game through it, it comes up with an error message and asks, if I want to open a log file. When I select yes, this is the logfile:

Starting log
GPxPatch version: 3.80
GPx version detected: decrypted GP4 v1.00
Verbosity level is 0

Executing gp4.exe
Error writing process memory: (487) Attempt to access invalid address.


*** error injecting code: (487) Attempt to access invalid address.


what can that be??? Where's the problem????

anybody??

post it on the Gpx patch forums...they no what all the error codes mean.

have you tried ticking the box on gpx patch [ start in debug mode ] try it in low or of just try all options untill u get the game going, i had same prob this fixed it

brian thanks,

but it was a virus which copied itself into the gp4.exe file so I tried to replace it with the original, but the nasty virus took action again, after all the effort I decided to reinstall winxp and now it works ok...
