Reinstalling the game

I have been fighting some technical problems with the game that have gotten progressively worse. My next step is to reinstall the game but I want to make sure I don't lose anything. How do I ensure I don't lose my account information, character stats and inventory and all that stuff? I've worked on the character for a long time and don't want to lose anything. Thanks -JoeB

it all stored on the server

account information is stored on the server. you will not lose any character data. the only thing i am unsure of is the keyboard binding. this used to be stored server side on a character basis, but i am unsure if it still is.
