Would you happen to use spybot search and destroy? If so, your gonna have to allow BiA to run in spybots preference. I had the same problem until i allowed BiA in spybot. If you don't use spybot then it might be another type of spam/pop-up blocker u have thats conflicting with the MP side of BiA. If this doesn't work and if your net is through a router, u might have to forward your ports. search google on how to forward your ports on your router if this is the problem.

Try to update your ethernet drivers. Usually these types of drivers come with a full motherboard driver. If this doesn't work, all i can think of is to re-install BiA and see if the problem still exists. Reply back and we'll go from there.
