Chearry, make sure you post your own thread when you have issues in-game, please. (Although reading these comments will likely answer your question). And nu, movie clips are not the issue.
To retrieve your character, log out and then log back into the forum and look at that golden box at the top right of the forum. The link that says "Character Reset" is what you use to reset your character's home, and return it to Lonely Cave (or wherever you'd set your home). Do this, and you'll have that charrie back.
(Elaborating on what Starrk said),
As for Fluorite, it's likely that the map being so full right now is making it difficult for you to enter. However, I suggest giving it a few minutes and trying to enter again. Turning off Water Reflection (Options>>Video>>uncheck Water Reflection) and turning down View Distance (Options>>Video>>turn down View Distance) will lighten the load on your computer when you enter this typically lag-heavy map.
