I just tried to get on RCGroups and had the same problem that you had. I had a similar problem last week, but was able to get on several hours later, so I'm thinking that its their problem, not yours. Try several hours from now, but meanwhile, browse these forums.

I'm listed on RCUniverse, RCGroups, ********* and RadioControlZone under the same name. Usually I'm in the Beginner or ParkFlyer forums. See you around.
