Fanpop wasn't letting me log in after I disconnected my Facebook account to this account- why?

My phone is good but an outdated model, and one thing about it is, the login with Facebook button anda see on Fanpop isnt there when I got to FP. I got tired of this because I wanted to use FP when I was on my phone so I disconnected it on my Facebook. but then I still couldn't log in- none of the three passwords I used worked! and when I tried sending it to my email, it berkata I have no e-mel registered since when I made this account I might have connected to to Facebook when I registered. what do I do? I'm absolutely positive the passwords are right.

This is frustrating me to no end. I'm thinking of just making a new account but I like this one since I've done so much on it.
