Hi,
I might have a slightly different problem. I´m using win 7 and have recently acquired the Origin Ultimate collection due to my discovery that many of the cnc games are censored in the German version. In any case I´ve finished the campaigns yet again and discovered cncnet a couple of days ago. So obviously I want to play RA2YR revenge online. However, though I could play RA2 and YR with the regular installation just fine in both LAN, skirmish and campaign, the majority of Multiplayer matches that I start, using cncnet, I end up with a black screen and sound. Is there a fix for this issue? Like I said I have no problem playing the game without cncnet in 1600x900 resolution with the lanpatch installed. I'm playing on a laptop with a Nvidia Geforce GT 740m card.
