Unity 3.0 socket security has completely stopped game network running (help!)

Hi,
We've got a game running its own network using sockets, however an upgrade to 3.0 with the new security sandbox has completely stopped it working. We've tried everything we can think of and it won't come back up, so could really do with some help!
'sockpol.exe' doesn't work so we've tried putting the crossdomain.xml file on a webserver at the same IP, then used PrefetchSocketPol on port 80 with no luck there. Wierdly attempting to connect to a socket on 127.0.0.1 doesn't work either, nor does connecting to a socket on 127.0.0.1 with PrefetchSocketPol and a webserver on the same machine. We've also tried creating a server using the sockpol C code and running that, with nothing there either (Just keep getting security exceptions).

Any advice would be really really appreciated!

Game Port: 3200

Edit: Oops - this thread should have gone in networking.

 

Fixed the issue - thanks anyway everyone
