yes i faced the same problem, tried different varifiers, and a bunch of other stuff, tried different host files. i then tried to search the net if anyone have the same problem. but so farm im still clueless about it b/c yesterday everything worked fine, i didn't make changes to my windows, no updates from server and now BOOM walker freezes after 1 min and it doesn't look like its walker. it looks just like server blocks packets from l2w.
