Can I reinstall Quake 4 without losing my games?

Basically I'm only half way through Quake 4. I'm not very good at games so as you can imagine it's taken me a long way to get where I am. Whenever I load it up now it crashes, and takes me back to windows.

Should I reinstall Quake 4 over the current installation?
Should I uninstall it, and then reinstall it again?

Will I lose my game data?
