why can't i open my acc..its said that its is suspended when can i use it..??

You'll need to send a ban appeal ticket to: http://www.aeriagames.com/contact/ban
As account ban or suspensions are not talked about in public threads. I'd also advise to check your email to see if you recieve an email about what happened to your account. It's also adviseable to look in the junk and trash mail folders, as it could have accidently endded up there.
