    Not sure why the update button isn't working, but start by installing Zotero 5.0.69 from the download page to see if that helps.

    Will I loose my library? I worry about this. I did not connect it to the online account. It is just on my comp

    No, it won't affect your data in any way.

    (In general, of course, you should always make sure you have a backup of your Zotero data directory, or ideally just your whole computer in an automated manner.)
