Hi
I would do what Saltgrass suggested and uninstall the software, and then reinstall it again and see if you can get back where you were.
It's possible that if the problems were caused by and update from Microsoft that installing it after the update is already there will fix it.
Once it's uninstalled run CCleaner, and clean the junk and left over registry entries.
It wouldn't hurt to run Malwarbytes too just to be sure.
If possible reinstall in a different location then the original one, even if you just rename the folder NewTMTinstall, or something like that.
That will help keep Windows from seeing it as the same software and not pick up errors from the original installation.
Make sure that MSE is turned off while...
