I recently bought two copies of EE2 and am trying to use it to play a game over my LAN. Support has sent me two keys. Both of them have .7z extensions, but won't open with 7zip or WinRAR.

1) Are they corrupted or am I just screwing up?
2) How do I use them?

Barring that, is there a workaround for the CD key issue? It looks like the cfg file with the CheckCDKey flag isn't in the same place as it is for EE1, so that procedure won't work.

Thanks for your help!
