I'mLost' - apologies back to you for the late reply :-)
Are you on the latest version of PM? It should be 28.0.0. You knew how to do the other stuff I mentioned, so I'll assume you know how to check the version & then for updates.
When you restarted in "Safe Mode", was the bar visible then? If so, it might be worth disabling any add-ons you have, one at a time, until (hopefully) the bar appears in "Normal" mode. Whichever one you turned off at that point *might* be the cause of the problem.
I've had a look through the Forum & there isn't much to go on, as you've discovered yourself - perhaps if disabling add-ons doesn't bring any joy, post a Q of your own there?
