Speedgrade won't launch - Splash Window then nothing!

Question

Hello,
I have had an issue with Adobe Speedgrade CC 2014 not launching either stand-alone (just launching the app) or by using the Direct Link from Premiere Pro.
The Splash screen appears, then vanishes without showing the software. Basically, it looks like this after attempting to launch the app.
After that, the splash screen vanishes, and I'm left with this:
The Speedgrade app doesn't launch, and the Speedgrade Menu Bar item doesn't do much; it allows me to quit the app, or I can force quit from the dock.
This happened to me before, and I contacted Adobe Support. They logged into my machine, and did something with folders and the like, and it seemed to work for a few days, but they did not tell me WHAT they had done. My attempts just now to recreate those steps have been in failure.
Here is what I have attempted:
Opt-Shift click to launch Speedgrade, to skip Preferences.
Trash Preferences.
Uninstall-Reinstall Speedgrade.
Run the adobe CC Cleaner app.
Restart my computer.
The computer I am using is a MacPro tower, late 2012.
3.2 Ghz Quadcore Intel Xeon
20 GB Ram
ATI Radeon HD 5700 1024 MB Graphics
OS is currently on 10.10.1, and Speedgrade is fully up-to-date, as is the OS, I believe.
I'm unsure of how to proceed, but would love to find a permanent solution. This is the only software in the Creative Cloud that is 'acting up' on me, and it was becoming one I had hoped to use more frequently....sadly I won't be able to do so if it fails to launch like this again. I would like to be do this myself without needing adobe support to log into my machine, as I don't recall what they did exactly, since they merely left me with a 'okay, it should work now.'
Thanks for your time!

Yes, there have been others with similar issues. Perhaps a bit more to the Mac side of the Grand Divide, but some in PC World also. There have not been a *lot* of users with this, but some ... and for whomever this hits, it's not a minor issue, is it?
As to other software ... yes, there have been instances of PrPro & Ae having the same problem. There's a lot fewer installations of Sg (as far as I know) than either PrPro or Ae, so I've no clue as to percentage of this per program in a relative sense.
As I've noted in another thread, in a few cases the "solution" was based in Mac OS ... someone finally re-formatted their machine, re-installed their OS, then all the flipping programs on the rig ... and when firing up their Adobe DVA's, the offending program worked as per expectations after having been through every flipping thing anyone here or Adobe staff could think of without success. As I'm thinking about it, I do recall one PC user reporting a similar thing ... completely re-formatted and then things just worked. On the Mac side, there've been a couple dot-releases of the OS that have been notable for having problems here, and by reverting to the previous OS release they got back in operation. I don't know which particular numbers those are.
Re-formatting and/or reverting is a time-consuming and frustrating/painful process for most of us. I don't recommend doing so. I'm just noting that for a few, it's been an OS issue, something they couldn't find but clearly with re-installing their OS, stopped being an issue. And a few people have then tried it ... and ... just had all the pain & none of the success.
At this point, I'm gonna reference Dennis Weinmann and Fran Roig who are both engineers on the Sg team and work these forums when not buried with little things like say, reworking the program itself, as they have the tech knowledge of all the under-the-hood things that might be of useful assistance. I can speculate ... they could probably help. Or Kevin-Monahan who's more known for being on the PrPro boards but does help here some also ...
