ADBP 1.5.0.0 on IE 11 not blocking YouTube in-video adds.

I cleared the cookies and temp files again, and reset IE to default (except the personal settings), no more ads after I re-enabled ADBP. hurray.

I guess I spoke to soon, after watching a few ad free videos I started getting ads again, and the skip ad button has disappeared again.

Recheck "Enable 3rd party programs.." (Internet options/Advanced tab). Also check that ABP is still enabled in "Manage Add-ons".
Have you scanned for malware?

Enable 3rd party programs was still checked, I scan for malware regularly, but ABP was disabled - enabling it fixed it.
It was the resetting of IE that fixed it, but I think that was also what disabled ABP, It has stayed fixed for about a week now so I think it is truly fixed now - Thanks guys.
