I recently updated to version 1.8.2.on mac. It worked for a few days but now at start up i get an error

> heightOfLastBlock must match chainHeight

Now it’s stuck on “connecting to bitcoin network”  
If I try to reinstall will I lose all my data files? Like my backups and everything else?  
What should I do to fix this?

I’ve reported bug to Github, it’s #6037
