# Eondude :
I installed the unofficial beta patch or build, watever you call it. Arma started acting weird. So I reinstalled arma OA. But no success. There might be other reasons that I might not know. Plus I used six updater to install day Z mod
When you reinstalled the game, did you completely uninstall everything first including the folder which may
of been left after the uninstall? cleared your keys too in the regedit?
Another thing is, how about any other games, they are still working ok playing multiplayer obviously using the
same router? I doubt this has anything to do with the router or firewall itself as you said it was all working
fine prior to the install of the beta patch. So we can most likely rule out the "router" and "firewall" problem.
You didnt change drives did you? for example the first install was on the C drive! but now you moved it to D drive?
This could be a permissions problem with your account for that drive.
*Just to clear this up about the router, while your at it, reset the router and rerun everything
again to try that, though if other games are running fine on multiplayer then no need.
