At this moment (3-feb-11 around 17.00 GMT+1) I have trouble connecting to Warlight. I see 'Loading your games' until eternity eventually getting this error:
completeHandler 34::warlight.shared.messages.ServerException Error (0): WarLight Server returned ServerError
at main\MyGames_.as:EndGetMyGames()
at warlight\shared\messages\Messages.as:GetMyGamesReply()
at warlight\shared\messages\Messages.as:OnReply()
at warlight\shared\messages\MessagePump.as:OnReceiveMessage()
at mobileShared\Messaging.as:completeHandler()
at mobileShared\HttpRequest.as:completeHandler()

Is the server very busy, or do I have to check some things at my side?

I'm having the same problem as well.

i was slow about 30 seconds ago

yeah it was slow for me too :/

Thanks for reporting this. It seems to be fine now, please let me know if you run into issues again.
