Game hangs at "Receiving Data"

[n0aim 10]

Hello everyone,

I am having an issue with my ArmA hanging at the "Receiving Data" when I'm about to get into a game on multi. It started friday night, so far I have done this:

Re-downloaded ArmA2 (Steam)

Re-patched to 1.05

Re-download ACE mod

Re-installed ATI Drivers (4850 CrossFire)[Latest drivers and previous]

Re-installed .net framework

Ran virus, spyware, adware and registry check.

I also seem to get slot problems, as sometimes I can't see them at all, sometimes I see SOME slots, other times I see them all or even see people in independant/ civilian/ opfor when it's a BLUFOR only map.

Thank you very much for reading.
