When Installing, Creative Cloud Tries to Validate with a Strange Email Address

I'm not really sure how to describe my issue - I get no error code and I have no idea what would be causing it, but when I'm installing Creative Cloud, after it has me enter in my email address to sign in, it seems to append some string of characters to the end of my email address and try to send an email there instead of to the adress I entered for verification. 

Of course, I don't receive that email and can't verify. 

Obviously, I don't know how to fix it. As I investigate further, any advise or tricks would be appreciated.
