Global Entry Registration Problems

I went to global entry registration page and proceeded to register. Filled out the first part hit next and then put my information in and selected next. It then brought me back to the page I started with including The Warning message about multiple accounts. At this point I don't know how to proceed? Has anyone had this problem? I tried calling and the line is busy. In addition the e-mail said it could be 3 to 5 weeks to get back to me.

Been quite a few years since I registered for GE...

-Did you set up a previous account? What happens if you try to recover the password or similar regardless of whether or not you think you have an account?

-What info did you enter that allows it to determine there's a duplicate account? Is it just email/DOB/SSN etc.? If it's thinking it's a duplicate account based on email alone then use an alternative email address.
