Since Snow Leopard 10.6.7, Apple has not used Adobe. This is the reason that when you go to the Adobe site, it doesn't say it supports Lion or anything about 10.6.7. Ever since 10.6.8, Apple uses Preview to open pdf files.
If you are interested in the fix, I have the guys email. He said he would be more than happy to help with whatever needed to be corrected. The bad part is, our offices are closed until Jan 5th and I left it there.

On a Mac with lion?
