A serious error has occurred or how the 7.1 update ruined my life.

Question

Ever since the 7.1 update to Premiere, I've had nothing but problems. The desktop app fails to update for every update, and appears to think it's out of date when it's not and then the icon in the menu bar will be grayed out until I reboot 3-4 times. The "workaround for that seems to be to force quit and uninstall the "previous" version and then download the "new" version from the creative cloud web portal. This wouldn't be that large of an issue, but it happens almost every other day.
Then once I can actually open Premiere, the real fun with errors begins. I have received the "A Serious Error has occurred" screen on 30-40 (not exagerating) delightful occasions in the past couple of weeks, with no real details of what is actually wrong. It usually occurs while trying to fix an issue where my multi-clips aren't showing the audio waveforms in the sequence, but it has happened plenty of other mysterious ways. This is even more complicated, because it's happening on multiple systems and one of them isn't even using the 7.1 update and another is offsite and using different hardware. The same annoying error occurs across them all.
Another super cool "feature" is that Mercury Playback Engine capabilities come and go as they please. Sometimes they work for Premiere or Media Encoder or After Effects, but sometimes they just pick one for that given day and don't let the other apps playback. All of the systems GPU were working just fine in 7.0.1, but now wtf Adobe?
My system specs are varied, but the general idea is this:
Mac Pro systems (4,1-5,1) 2.3GHz - 2.93GHz
16-24GB RAM
Nvidia QuadroFX 4800, Nvidia QuadroFX 4000, Nvidia GeForce 9800
OS X 10.7.4 and 10.7.5
A few of the systems have AJA Kona 3 and Kona 3G
Most of the media is being accessed across 10gigE to a ProMax Platform, and the project files are local on SSD's.
I have the bug report from Apple, so if that helps let me know so I can get that info to someone who cares.

Hi Kevin,
I'm still planning on attempting the 10.8.5 install on one of the affected systems. In the process, I have uncovered a new issue related to the CUDA acceleration not being there at all on a system that used to have it. That particular Mac Pro system only has a GeForce GT120, but the point is that in CS6 and CC, the CUDA was working until this latest update. The other systems have QuadroFX 4000 and 4800 cards, so those seem to be getting CUDA playback, however it is intermittent.
As for the OS X 10.7.4 not allowing me to install 7.1... That is correct. The Creative Cloud Desktop app was failing updating itself (as it still does on every "update") quite a bit, I don't remember any specific messages, but I did see somewhere along the process that I wasn't able to install the Premiere 7.1 update with my 10.7.4. One of the systems here is have a ton of issues with AE, but that's a whole new thread I think. I will attach some of those errors for kicks, but all of these problems occured with the introduction of the virus that is Creative Cloud into our working environment.
I am working with a wide variety of media: R3D, 5D, F55 4K XAVC, Canon C-300, XDCAM EX, FS-100, ProRes. The projects that I've been having the most issues with lately has the Canon C-300 .MXF media mixed with 5D h.264 as a 2 camera multi-cam set up. The other project that was giving me a lot of trouble right when I installed the Premiere 7.1 update was R3D and F55 4K XAVC. Both issues were the "A Serious Error has occurred. Premiere will try and save your project" vague warning. I usually only lost work since the last Autosave 20 minute interval, but sometimes that is a lot of work and when it happens 10 times in one day, that is unacceptable.
Here are some answers to some more of those questions:
What other software are you running?
These are all possible conflicting software (IMO) that are installed:
Final Cut Studio 3
Avid Symphony 6.0.3
Cinema 4D R14
RED CineX
Davinci Resolve
Nuke7
Adobe CS5.5 and CS6 are still installed
Do you have any third-party effects or codecs installed?
Yes. Trapcode Suite, Primatte, lots of scripts in After Effects. Lots of codecs installed from Sony, Avid, RED, Canon, etc.
I think I've answered most of the other questions in this thread, but hopefully that helps. I will update when I'm able to get 10.8.5 installed. I suppose a clean install of 10.7.5 perhaps might have the same chances of fixing this as well.

Here are a series of AE errors, that might need their own thread:
