I just got the nano edition of this game yesterday

when i login it said An Error has Occured Please check your network connectivity [from Demo through the release game]

but I can play it through VPN

Now today I open VPN and the game can't login it said An Error has Occured Please check your network connectivity

someone can help?

PS. forward port/System Locale change/ delete wireless network /install patch can't help me to play

I have the same issue. Yesterday it all worked fine - today I'm getting "An error has occured. Please check your network connectivity" when I attempt to log in into Crysis 2, although I do have internet access.

I have Limited Edition, but I don't think it is relevant - it appears to be an issue around the login servers.

Edit: appears to be a known issue, according to EA support. Lets hope they fix it soon.

I have the same problem here!
We need a solution!!

I had this messege all the time an error has occured please check your connectivity network
I never played MP because I can't log in because of this error
what I did is that I updated my hardware system and it worked for me
and I logged in and I played MP but only for 2 days
today I tried to play but I have the same messege again !!!!? an error has occured please check your connectivity network
I have internet connection I can log in to other EA games such as BFBC2 & MOH but not this one !?
what is this error any way !!!!!!

I just installed the latest patch (1.2) and now I'm getting the same error so no more MP.

Enabling the "Windows Connect Now - Config Registrar" seems to have fixed the problem!
