So, I bought Crysis 2 off Origin a while ago when it was on sale, and wasn't able to login in the game, despite being able to do so here. Saw that it's "being investigated" in the support FAQ, so I left it for a bit. Tried again today, and still get "Invalid Login Details", and a message under the login window saying Invalid Serial Code (I don't think I've ever even entered one yet). I can login to this site fine, and I've tried changing my username and password. No luck.

I've noticed a few other folk have had this problem, but haven't seen any solutions on this forum. Did anyone finally get round it? Are crytek still investigating the issue? Have people given up/got refunds?

Type in your serial code when prompted, then if you get error, press "Skip", then go to "Multiplayer" and try again... It worked for some people.
