I'm having the same problem, with me though its Norton anti-virus saying it is a Downloader virus. So just wondering if anyone else has nortons having this problem. I did delete the beclient.dll so it would re download the update downloads ok but I join a server come out and try to join another and then get the error corrupt data #5. Nortons had an update last night/early hours of this morning and seems to be related to whatever updated I am guessing its a false positive as I thought instead of going into a Breaking Point server I would go into a normal server so it would download the update through a different server and had the same problem.
