Skype for Business No longer launches; "Stopped Working"

Running Windows 7 Professional and Office 365 Professional which included Skype for Business. When I installed Office 365 Pro the other day everything was working just fine. This morning I updated iTunes and rebooted. Skype for Business no long loads now. I get the "Microsoft Lync has stopped working" with the usual two options to check online for solutions or close the program.

What I've tried:

-I already tried rebooting again, didn't work
-I ran sfc.exe /scannow and that found no errors.
-Ran CCLeaner Registry cleaner to see if it found anything broken related
-Ran the quick repair for Office 365, nothing...
-Ran the full repair for Office 365, nothing...

I'm at a lost here. One thing I did notice though when I try to launch it, before it gives me the error, my desktop icons "flash" as if its attempting to do something with explorer.exe.

Any help would be appreciated!

Hi macpro88, welcome to Windows Seven Forums.

I am not familiar with using Skype for Business, but this MS website might be helpful. Read right through it as there is more info well down near the end.
