As said above, please search in other threads before creating a new one. Only in this page of the forums, there are three threads about the subject. Anyway, the server is seeming to have this sort of problem lately, a lot of people are unable to get in Fluorite. It happened to me three times already, and probably won't be the last time it'll happen. While you wait for a MOD or Admin to restart the server and fix everything, try creating a temporary account or logging on another account of yours. Maybe in that account, you'll be able to log in succesfully, at least, I can. Good luck!
Unfortunatelly, no one knows when it'll be fixed. As I said above, it'll need a server restart for it to be fixed, and as far as I know, only an admin can do that. Since it's Saturday, that might take a while, but if you create an temporary account, it might work untill the server works.
