I could not register my wd2go.com

when I tried to register to wd2go.com from my cloud dashboard I got this error on my email:
The web access account you requested for could not be created. Ensure that you do not have any network connectivity issues and try again. (250006).

but when I tried to add another user with different email it is done!

how can I solve this problem
