I followed the directions from this guy... I downloaded the worldguard release from his link provided at this forum thread http://forums.technicpack.net/index.php?topic=7444.0
Anyways... An older version of worldguard will solve your issues. I hope i have contributed back to the community that has given me and my friends hours of help... If it wasnt for this community i would not have the badass server i just made. Its probably the only encouraged nuclear war server thats grief free... lmao...
