KnowledgeBase missing?

Hello,
It appears the entire KnowledgeBase has disappeared from the server.
I've tried for several days to access it.
Below are the errors to either the home page or a specific link from File Exist Rules
Just thought you should know.

Database error: Invalid SQL: SELECT f.id as id, fs.name as name FROM file as f, filesystem as fs WHERE fs.fileid=f.id ORDER by f.created DESC LIMIT 5
MySQL Error: 145 (Table '.\kb\file' is marked as crashed and should be repaired)
Session halted.

Thank you a lot for letting us now.

The problem should be fixed now.
