Can't log in on two characters

[twac87]

I am having trouble logging into two of my characters. One is in North Freeport and the other West Freeport. All of my other characters work just fine. For these two, however, when I try to log in, the loading screen stays up and never loads the character. I tried reinstalling, thinking that my zone files had somehow been corrupted, but this did not solve the problem. Character names are Morlo and Trebel. Please help.
