Migration Email is not valid

I am trying to migrate my account and something is not working out.

I filled in the email I use to play warrock multiple times ingame, after launching it, but so far I haven't received an email yet.

I also tried to verify it here: https://warrock.papayaplay.com/warrock/verify.do , but there I get a message saying: "Email is not Valid". 

At this moment I'm running out of ideas and starting to get nervous because I don't want to lose my account.

Any ideas?? Thanks in advance!

Greetings,
