There's not much you can do imo. refresh browser sometimes helps. closing/restarting rf2 is a good routine. I hate to say it because this advice is being given way to many times on just about every issue, but if you have auto-updated for a few builds maybe re-install and start fresh. or install a separate rf2 to see if it works.
Thank you my friend. I have tried all this. Looks like I will sit here and wait Typical, the wife take the child out for a few hours and I spend it trying to fix RF2 instead of playing it.
