Combat Arms and f2p

1) Does anyone play Combat Arms ? I keep getting the same error saying I couldn't connect to the server and to try again later , error code PI blablablA...

Anyone knows how to fox it?

2) Are there nice free2play FPS' or MMORPG's ? Tried America's Army (pwned my low PC ._.) , Silkroad (too much bots/goldbots and I don't understand Korean so I could only play on shitty euro servers) , F.E.A.R multi (haxxed and not that fun) , Warsow (Not my style of game)
