Black Building Syndrome

Black Building syndrome ...

Hoping someone can help with this problem.

I am unable to join some co-ops. I get as far as the black building lobby which does not populate with any text/ choices etc.

This is driving me nuts and spoils everything for my friends who have to change hosts (and then I can join - strangely enough).

I am in Australia and they are in US/Canada. But it is not a ping problem, usually 220 - 320, because I can join some but not others. Its not a D Server issue, I have re-installed the game, removed all mods. Checked router port settings.

The same host can host a dogfight - no problems there, just co-op. ????

Is there something I am missing ??

Cheers and thanks guys.
