Thanks Happyone for making it so easy to solve this problem. I spent a lot of time yesterday trying the unzip/zip change bootstrap solution but I am too unfamiliar with these things and failed.
I confirm what the previous poster said: this great offering by Happyone will not work with TB 58 Beta. But it works like a charm with the previous version 52.5.2
Download the file from the link Happyone provides, then go to your TB 52.5.2, click on the menu (3 lines in top right hand corner, go to add ons, click on the wheel for a drop down menu, choose 'install add on from file' , browse for that file and install. Thanks again.
