My Armada II client crashes whever i try to load the game.
I can load the "launcher", clicking 'launch fleet ops' brings up the splash screen then an error message:
"armada 2 has caused an illegal operation blah blah blah"
debugging the error gives: "Unhandled Exception in Armada2.tgt (NETWORKMANAGER.DLL) : 0xC0000005: Access violation"
Steps i took to get the error:
1) uninstall everything
2) Install STA:II
3) Patch to 1.1
4) Play Game (works fine)
5) Install Fops v3 Preview
6) Try and play (got error)
7) Install "V3 Preview Patch 1"

Try and play (same error)
I can still play Armada II (without fops) jsut fine, so i assume my client is ok.
