I recently bought a Vivitar 90/2.5 Nikon AI mount to use with my NEX. I bought a Fotga Nikon-NEX adapter from eBay. I mounted the lens but now cannot unmount the adapter I know Nikon turns clockwise to unmount. I am rotating it clockwise while pushing the little tab on the side of the adapter downwards, doesn't seem to do anything. Is there anything else that I am missing?

I have found on a couple of adapters that the tabs don't always disengage the locking mechanism properly. I fought one over the weekend that was stuck (C/Y-Nex) and had to use pliers. Serious and repeated pushing and wiggling seemed to be my only recourse. I eventually got it off by pushing (with the pliers) on the base of the knob rather than at the top as the pin coming out was a little bent. I'm not sure that will help with the tab style on a Nikon though. You could try a very small dab of alcohol if you think it's jammed (or just drink it)....

I learned from last time when I described Iso Propyl Alcohol as IPA
and we call it ISO at work which might also be confusing in the photography world ...

You might want to try wiggling the lens back and forth a bit while pushing in the lens release. Sometimes the locking pins just need some encouragement to retract.

I had an Adaptall lens in Nikon mount get stuck to an EF adapter, the Adatall mount was aftermarket, I had to take it home to separate them, I had to push the release while turning CCW then change directions while still pushing the release to remove it.
