WIndows Store On 8.1 Stopped Working

Hello.

The "Windows Store" on my laptop ceased functioning a while ago. I was poking around trying to fix it.

The Windows Store appears to work on the other (non-admin) account, but none of the apps work (they have those black-on-white 'X's).

I ran "wsreset.exe" and I got:
"windows cannot find 'ms-windows-storeurge caches', make sure you typed the name correctly and then try again".

I ran "AppsDiagnostic.diagcab", and got:
"Windows Store cache might be damaged
Windows Store configuration might be damaged"

From here, "http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_store/how-to-fix-windows-cannot-find-ms-windows/a88b796d-30eb-4f6f-9af1-fca09779cf6f?page=1", I tried
"powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml", and got:

I ran "sfc /scannow", and got:
"Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in offline servicing scenarios."

I don't want to loose my installed programs (they are more important than the apps), so I am hoping to avoid refreshing or resetting.

Any ideas about what I should try next?

Why won't MS allow us just to re-install the Windows Store?

Thank you for your time.
