Need help with a glitch

Hi,
I'm new here and i was wondering if anyone knew how to fix a dark square that i got from using a co2 server to play co1. the dark square is around my level 110 super sword and it shows up on everyone's who has that weapon. If someone can tell me which files to modify to fix this problem i would really appreciate it.

hmm i would say... dont use co2 on co1 that should fix any problems ;p

yea i suggest you dont use co1 on co2. i got arrested twice because of it. (i think)
