Forum xd_arbiter error
 

Whenever I visit my vb4 forum I keep getting this xd_arbiter error prompt thing that is tied to facebook? Is there any fix for this? I am on a new computer by the way running IE8 and chrome. A gateway E-4100. I was previously using a gateway ev700, and wasn't getting this error. I don't think it's my comp or browser as I did some google searches and have seen others having this similar issue.
