Nope, didn't even get as far as choosing a server all weekend. I send them off a whole load of diagnostics as requested on the official forums but just a generic response saying they received it.
Its something client related, since there were people who had done previous beta testing with no issues seeing the problem so they should be able to fix.
The problem is basically hardware incompatibility so I just need to save my pennies faster and buy a new rig.
