PP 2014 8.1.0 When I "Save As" my project, quit and close, the new project freezes on launching

Question

iMac (Retina 5K, 27-inch, Late 2014)
4 GHz Intel Core i7
32 GB 1600 MHz DDR3
AMD Radeon R9 M295X 4096 MB
Mac OS Yosemite 10.10.1 (14B25)
PP 2014 8.1.0
Blackmagic 4K media working in 4K sequences.
In my current project, I've been experiencing very strange crashes upon launching PP. Before ending my work for the day, I usually save my current project manually, and then do a "Save As" with tomorrow's date at the end, (projectname_2014-12-02) so I have a fresh copy to begin the next day and still have yesterday's as a backup. I then quit PP as normal. No issues. In other words, it closes just fine without any crashing or odd behavior.
In the last week, a rather annoying issue has presented itself. Once in a while, that new project that I created with Save As, will not open. I opens to the point when I can see my bins and my timeline, but as I would expect it to begin propagating the timeline with media, I get the spinning beach ball. I can wait for hours, and the project never loads. I can go back to yesterdays project and open it just fine, but any project saved with Save As, very often seems to be corrupted.
Except, that I can open it up fine on another machine. So it's not really corrupted. And it doesn't happen every time. Just most of the time in the last week or two.
I've done the following troubleshooting several times. Restarted the computer. Repair disk permissions. Launch PP with the option key to clear preferences. Cleaned the media database. Tried launching the project with all media offline. Uninstalled and reinstalled PP. Booted from USB OS install drive and repaired permissions, repaired HD, and even reinstalled the OS (not a clean install, just over the top of the previous one).
Once a Save As project won't open, it's done and I have to go back to yesterday's project.
Now here's where it gets really weird. If I create a new project, and import one of the "won't open" projects, not just a sequence, but the whole project, it's fine. Which of course isn't entirely surprising.
What *is* surprising is that after I save and close that new project with the old imported project in it, I can now go back and open all of the projects that would freeze on opening just minutes earlier.
Everything is right as rain again. I'm glad I have a work around, but it's a little unnerving and random, not to mention time lost troubleshooting this bizarre one.
Anyone else had any weird issues like this? Thanks for any thoughts.

Attached is Dennis Linam’s Audition – “Log File” and “Log – Last File”
Contact information Dennis [email protected]
Previous contact information with your organization (DURIM):
Dennis - i just finished my audition trial and bought the subscription the 2014 version.
created by durin in Audition CS5.5, CS6 & CC - View the full discussion 
DURIM - Okay.  I would expect the "Cache Warning" message because your default directories would not be the same as the ones in the settings file I generated.
If you go back to the "7.0" directory and open the "Logs" folder, can you copy the "Audition Log.txt" file and send it as an attachment to [email protected]?  We'll take a look in that logfile and see if it gives us more information about why this is failing now.
Also, do you have any other Adobe applications installed on this machine, such as Premiere Pro?  If so, do they launch as expected or fail as well?
I do have the trial Pro version of Adobe reader, but I have not activated it, because I fear the same thing will happen did it. I cannot afford to activate the subscription for that product and take the chance of it not working either. I depend on those two programs religiously. Here is the files that you requested. I appreciate any help you can give me to get this audition program started
