There is no other way to change your account password if you do not have access to the email your account was registered with.
Did you give your password to anyone at all? If so you are always at risk, unless you change your password later on.
I didn't but recently I had a virus on my comp, keylogger or something it get my Facebook pass, hotmail, other games logging... My friend from USA said he played with "me" but it wasn't, that's when I was sure it was hacked. Can't any admin change it for me?
Key loggers are indeed a very serious threat hopefully you have removed it off your computer completely now. You may contact the game developer through these forums by creating a conversation with him or you may email him here. kyle@shellshocklive2.com and hope he responds soon. Good luck.
