Hey dudes and dudettes!
I haven't seen this on the support forum yet, so I have a sneaking suspicion that this is a personal problem. For C&C Generals: ZH, whenever I attempt to log in to the servers, it tells me that I can't connect to the online servers. Note that I had no connection issues earlier this morning, so whatever issue this is, it's been a rather recent development. Are the servers down? Is GenTool messed up? Will Sunny ever rescue Fido from the well?
EDIT: I've since seen another post that outlines the problem that we all seem to be having. Maybe this condensed version will be a little bit more helpful to some.
