Edited Unassigned: Can't Login to Editor [1899]

I downloaded the new 1.3.18.144 updated Editor and when I try to login to the Editor it makes the Computer's default error sound. It will not sign me into the Editor and I tried the last version of the Editor (1.3.18.143) and it's not working on that either. The previous version was working a few days ago for me. Also the email and passwords are correct (I signed into this website fine with them).....

EDIT: I was at my uncle's house when I first bought the Editor, then went to my friend's house a few days later and was using it there too. I'm now home and it's giving me the error. I guess my issue is the fact that I already used it at 2 different IP addresses? If that's the problem then can I get my uncle's IP address removed? I was only at his house for the week while I minded his dogs for him. I don't need the Editor to work at his IP anymore lol.
