I'm having similar problems..
I received the confirmation email about 2 hours ago and can only log into
http://x10hosting.com/account.
When trying to use the change password option on that page, i get the following error: "Invalid authentication token, please try again."
I've tried to login via ftp, but both when trying my subdomain.x10hosting.com and the ip addy, i get an authentication error.
Also when trying to login to the cpanel, it also throws an authentication error.
Any help would be appreciated.
Thanks.
Edit:
nm,
don't know if it was just a matter of waiting for settings to propagate or if someone fixed it, but seems like everything works now.
thanks!
