hello friends... i have a server connecting issue...its showing in connecting only and after a min its give error eveytime...well i played whole day but this problem never come to me,,,but after reach 25 level its giving me problem...plz help me out what i do?

It's a known error, take a look around this sub-section, you will see that alot of people have it.

ohk but why this happen after my reach level 25...whole day its working fyn

It has nothing to do with level, as a matter of fact, it has nothing to do with anything. For me, it only connects when the map is dome and this is really funny. But that's just how servers are working right now.
