Howdy Prebenjensen,
I am sorry updating has caused some hassle. I would love to help you figure this out.
First of all, it sounds like you are running an outdated version of WordPress. It is probably a good idea to upgrade that first. Tutorial: Updating WordPress and Making Backups. That backup outlined in the guide will be helpful too so you can revert things if something happens.
Once WP is update, try updating the plugins again. Simply clicking update plugins works 99.9% of the time. But, if for some reason that is giving you issues, you can instead do a Plugin: Manual Update. You can skip the step about making a backup since you will have already made one.
Now everything should be up to date, secure, and working smooth! Does that all make sense?
Cheers!
