SccProviderPackage package did not load correctly - VS2013

Question

Description:

Not sure what I did but one day Visual Studio Professional 2013 stopped launching. Unlike the other similar questions asked, this is using VS2013 and the app doesn't even launch. This dialog is all I see:

.

Also, here is the log file from VS if it helps.

What I've Tried:

• Going through Add or Remove a Program and repairing everything related to SQL (as per another question's answer)
• Repairing VS2013 (did not help, have done twice now)
• Clearing Team Foundation Server cache from C:\Users\UserName\AppData\Local\Microsoft\Team Foundation\4.0\Cache (and 5.0 and 6.0)
• Running devenv.exe as administrator

What I would like to avoid:

Uninstalling and reinstalling VS2013

Answer 1

Installed update 4 because I realized I hadn't yet and everything works now. I don't know what the underlying issue was but updating it fixed it.
