I am also having a similar issue, after clicking on the email to validate my address, entering address and password, i get the following error:
Unable to verify activation code, click here to request a new one
i am now currently locked out of playing the game as it wont accept that my email has been vaildated
If you have tried a different email on the account then best to call them , should be sorted quickly all going well
see db woodynz post here with a link to numbers and how to use skype if you have it.
Using skype with that contact is a free call to the best of my knowledge, that number is only available as per the hours listed (Support available from 9.00 CT - 21.00 CT) so need to confirm time zone etc
I had same issue just ended up using different devise
