PT 11.3 is a nightmare!!

I just upgraded from 11.2.1 to 11.3. For starters, the Bounce to Disc function is still NOT working and Avid claims that it's been fixed. And to make matters worse, now I cannot get the system to even record!! Imagine that, a DAW that will not record. So, since there is no way to do an uninstall easily with PT 11 (no uninstaller) I went to the Sweetwater website for advise (it came up first in the google search if I recall). They had a very specific set of instructions on how to uninstall PT 11 and I followed them. I then went back to PT 11.2.1 and when I opened a session I noticed that all my 3rd party plugins are GONE!! I do see the Waves V9 plugins in the Apps folder but PT 11 doesn't see them. Needless to say this has been one heck of an evening. Any suggestions on how I can get PT 11 to once again recognize all of my Waves V9 plugins and the other 3rd party plugins I have (Lexicon LXP Native). I am very disgusted right now with what 11.3 has caused. 11.2.1 worked fine except for the Bounce to Disc function. Thanks.
