I installed PT 8 LE about 2 years ago and used it less than 10 times. Compatibility issues. Now Im trying to install 10. Do I need to uninstall 8? I was under the impression they could live peacefully to be removed at a later date.... I will look for said application to uninstall. EDIT. I cant seem to navigate this simple software, this is the reason I stopped using this program the 1st time, this time I have more vested into using it so I need to make it work. I've googled and searched and read, where the heck is the uninstall button?
