Windows 2000 causing MAV with net commands

Hello, is Blitz3d fully compatible with Windows 2000? using a compiled executable (using the latest version of Blitz3d) and it seems that sending udp messages causes a MAV error. Do you know if this has got solution or is a problem of compatibility with windows 2000?

Thank you.

hmm i have a blitz exe on my remote win2000 machine which works pretty well with UDP commands. its not a compatibility issue then. maybe you should recompile it using debugmode for closer information.
