Running Guild Wars fine up until a week ago, when mid play it started to lag out. Provided pings of 70,000 and so forth. I quit it, presumed it was some one on the home network or a program on my PC. it continued to happen, whilst every other game i have ran without any lag what so ever. I could play CS:S or Company of Heroes, and they'd both run fine, but booting up Guild Wars caused my ping in game to shoot well into the thousands. It's not a firewall / antivirus issue and i have tried doing a complete re-install with no success.
No idea, completly stuck for ideas. Any help would be grand.
