Hi paulmessian

try to Re-initializing the plugins database and check it again.

thank you

Please mark "Solved" the answer that really solve the problem, to help others with a similar problem.

Ideato's solution did not work for me, but it gave me an idea...

Go to Tools > Add-ons

Then go to Plug-ins on the left, and check to see if Adobe Acrobat NPAPI is installed and enable. If so disable it. That did it for me!
