Delete Expired access token in MySQl database

I have a WordPress plug in that links in with LinkedIn. It has stopped working and is coming up with an error about an "Expired access token". See below

What I want to do is delete the WordPress plug in and do a fresh install. But when I do this and open up the plug in the error message is still present.

So what I want to do is remove any old access tokens etc etc so that when I do a fresh install then it system sets itself up a fresh.

So I am looking for advice on how I can do this.

This is the error report I see.
