I checked for updates within Abode's Help menu and there were none.
I reinstalled my Printer Driver and have selected the thumbnails to Print - Selected.
Nothing has worked thus far.
This is definitely an Adobe Reader issue. I will make sure to disable automatic updates to avoid this issue in the future....
My next step will be to uninstall XI and reinstall IX which is apparently more stable....
Update: SOLVED!! I installed Adobe Reader 9.5 and I can print. So in my case, Adobe XI was the issue.
