Ok I worked it out myself.
So for those people who are having this problem (and also those that don't know how to post you findings on help forums)
In the Acrobat>preferences there is an option called 'trust management' which is hard to spot because it is in a list of about 30 other items...
GOD I HATE IT WHEN PEOPLE DO THAT
THIS IS A HELP FORUM
I have the same problem, now that you have worked out how to fix it would you care to enlighten the rest of us?
