You should never ever modify templates in MASTER style (unless they are templates of a product you are deveoping).
Voila' ... the modifications were done on all templates. I was impressed!

I noticed though that the template I modified (which was for another mod) didn't work properly so I uninstalled it via the Product Manager.

You can't 'uninstall' templates vir product manager, only producst?

Unfortunately the templates did not revert.

If you manually modified a template in MASTER style, TMS won't ever revert those changed - as it has nothing to do with the modifications anyway.

Worse yet, I noticed for the first time a notice in German at the bottom of every page on the website that the template had been modified by the TMS system.

It is clearly stated in the readme.txt that TMS puts a branding in the footer.

All I know is if others are having this same problem I suggest this product be moved temporarily to the Product Graveyard until it is fixed.

There is no reason for such action; TMS runs fine on dozens of production sites.
