Premiere Pro CS6 serious error has occurred, crash troubleshooting

Question

ERROR MESSAGE: Sorry, a serious error has occurred that requires Adobe Premiere to shut down. We will attempt to save your current project
Problem: Starting last night Premiere would crash with this error message. This has been happening increasingly more over the past couple weeks, but starting last night and today - it has happened so much that I cannot get more than 5 minutes of work done without it crashing. It has happened on saves, renders, playback, switching active timelines, removing the mojo effect from a clip, and while sitting dormant. I’ve had the computer less than a year and hope that it is not a serious problem with my RAM or graphics card.
Using Premiere Pro CS6 - subscription based with latest update installed
SPECS:
MacBook Pro Retina, Mid 2012
Processor: 2.6 GHz Intel Core i7
Memory: 8 GB 1600 MHz DDR3
Graphics: NVIDIA GeForce GT 650 M 1024 MB
Software: OS X 10.9.1 (updated after problem started)
(nothing external from factory setup in terms of hardware)
Use an External USB 3.0 7200 RPM drive from OWC for project files
Use an External Seagate 3 TB drive for media storage
Using all DSLR footage from Canon 6D, Canon 5D mk II, and Canon 60D and audio from external recorders (.mov, .WAV, .wav files)
Third-party effects or codecs: Use Pluraleyes 3.0 and Mojo color from Red Giant
I realize this is a general error message and there are several forums posted from mostly more than 5 months ago. I cannot seem to find an answer that will help me. Here is what I have already tried:
1. updated to Maverick
2. checked for updates for Adobe software
3. Cleared the Media Cache
4. Switched from CUDA to software only
5. Updated CUDA and switched back to CUDA in premiere
6. Held SHIFT while starting up (nothing seems to happen or pop up on screen at least)
Next:
—Going to uninstall Premiere and reinstall.
Any suggestions or possible fixes are great appreciated. What should my next step be?

Answer 1

UPDATE:
STEP 1:
Uninstalled and reinstalled Premiere - worked without crashing for the longest time since yesterday. After 1 hour of running - it crashed once again with same error message and same report (see below).
Same as before:
Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000
STEP 2:
--Updated the RED GIANT plugin "mojo" (minor coloring software)
This worked for less than 10 mintues and then crashed again - but this time with different exeception details (I'm not sure what these mean)
Crashed Thread:  2
Exception Type:  EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000
Application Specific Information:
*** CFRelease() called with NULL ***
STEP 3:
Going off of the idea that it may be the plugin causing the issue (since it needed to be updated) I went into the project and deleted all of the files containing this effect in this project file (note: i have used this for 10+ projects on this computer with no trouble).
I thought it was fixed, from about 8:00 PM - 11:45 PM no crash - then as I was playing back clips - crashed again.
I have been loosely following these guidelines: http://helpx.adobe.com/x-productkb/global/troubleshoot-system-errors-freezes-mac.html
I am not sure where to go from here - should I continue into the "advanced troubleshooting" even though I'm not sure if any of these things are related.
IMPORTANT NOTE: I have launched two other Premiere Project Files (from previously completed projects) successfully without crashing. I tested a few things in the projects before returning to the problem project. If I suspect there is a problem with the file in particular - how do I find out what is causing the problem?
--I already removed MOJO effects thinking that could be the issue from the last files that were
--I have already gone back to a previous version from a week ago and imported the Sequence I needed. Still crashed.
I have sent 5+ reports to Adobe on the crash. Any feedback into this is much appreciated.
