Hi !
I tried the system just now and it works fine for me, I think you used an email address from a domain which is on the black list of our server (it could be with free email servers who are used to send a lot of spam). You can use your official email address here, we don't send nothing but service emails sometimes (for example: the site is down for.... blah blah blah), no spam or something like this...
Try to open an account on yahoo or hotmail, it should work...
Obviously fake email doesn't work, and the software waits 21 days for the activation and then erase the account
.
I hope this is useful to you
!
