Roblox won't Update

I just redid cleaning my Roblox files from my system, and I’m still having the same problems.

And now I can’t launch Studio either… So much for my gaming launching Alpha at the Maker Faire :confused:

I can’t even get ROBLOX to update/install at all now. It hangs right at the end of the installation cycle (from the look of the installation status bar).

Also ‘rbxcsettings.rbx’ in LocalLow (Windows 8.1):
rbx_evt_fmp=RBX_NOT_VALID&rbx_evt_ftp=RBX_NOT_VALID&rbx_evt_initial_install_start={“os” : “Win32”}&rbx_evt_initial_install_success=RBX_NOT_VALID&

I feel lame for doing this, but it’s still unresolved, so bump.
