So yesterday I was going to adjust my monitors' whitepoints. I opened up VECC to see the following...

No options appear at all besides power. The search menu will only show results for power.
So I tried removing and reinstalling VECC with plenty of reboots. The result? I still have no options in VECC - it's exactly the same. But since reinstalling, certain options have shot back to default settings - like the underscan on my 24inch LCD - it's now stuck with a 1-inch thick black border and I have no way to get to the settings to fix it.
I've tried using google like a mad man, however searching for something like "missing options vision engine" or any variant possible simply pumps out a few thousand results for people who can't get to Overdrive- not the problem I'm having.
