Company of Heroes: Opposing Fronts v2.103

[BarryB]

Did you install the one game on all 3 PC's?

[ASAD]

yes Lan work just fine

i tested it with some other games

its a original key, and the original game,
those 3 comps are using the same cdkey thats thats why i added the exe file so i can play with my bro on Lan

anyway i have the Original COH and it worked fine on lan using the same key on 3 comps

but after i installed the opposing Fronts, it had to go directly online, so i added the no CD/exe and RS file to go strait to the singleplayer and Lan

so what will the problem be? the exe and RS files or the serial?
