Helix Sign up Error

Hi, 

I've been having this issue for a couple of weeks and was hoping it would clear itself up by itself but it hasn't. I just recently upgraded my internet to Helix from the basic cable service a couple of weeks ago and was told I would have to create a second account on Helix as well as my old Videotron account. I tried to sign up and it asks if I have a Videotron account, I click yes, enter in my info, then it brings up a sign in form, I try to fill it out and when I get to the end with the authentication screen, it would post this error message:

https://zone.videotron.com/marvel/customer/registerUser: 400 OK

It won't let me sign up, or sign in so I don't have access to my Helix account. Has anyone else had this issue and how can I get this fixed.
