Son of Zardoz

I'm in the same boat. Had everything running fine for quite a long time but had to wipe computer a couple of months ago. Just getting around to reinstalling CnC RA 2 and I'm getting the same message. Ugh, want to play so bad.

Wasn't sure of where to put this as I'm a total newb here. Have always loved C&C Red Alert 2 and trying to get all of my computers good to go so I can play with my sons. Strangely enough, on my primary computer every time I have tried to do the client update it downloads quickly then hangs and never recovers. Is there a solution to this? Any help would be appreciated!
