[SL is kicking me out !!]

HI... I'm a legit SL user and it's sad to know that I'm unable to stay in SL not after I try to teleport to other regions! The only place I'm able to move is home and few places that's in my fav panel. I'm working on Lenovo G51 and has never caused any menace to support SL. Done with both firestorm and SL viewer but has not provided any help. Please help me to fix this ... Thankyou
