Issue| Wont log in my account

Hey,
After like 2 years plus i want to come back to GW.
Well, iv'e installed the game and in the log in screen i put my e-mail, pw and player name but it wont let me in.
I tried to send my email a new pw but it wont send me any, after like 5-10 tries..
I also tried to put my serial code in my NCSoft account but its saying my code is invalid, I've send them a mail too, no answers till now..
anyone can help me with this?
Thanks, Adi.
