Thanks you both for responding. It seems like I have made the situation worse.
First I checked all the fonts on the plan file and the master layout sheet. There only three types, Ariel, Helvetica and Abdi MT Extra Condensed Extra Bold. None of them Postscript.
I then reinstalled the OS 10.6.3.
Then I started AC 12 and the following pop-up message (see attachment), basically saying I should install QUicktime 7 or later. Mind you I already had Quicktime X (pro version). In my haste I deleted from my computer (now probably have to pay for it again, since it's a pro version) and tried to install the standard Quicktime 7 freshly downloaded from Apple's website.
An error message comes saying Quicktime 7 can't be installed because I already have Quicktime X in my computer! I did the Spotlight search and came up empty. Restarting the computer and repeating the steps didn't help.
I also downloaded the installer for OS update 10.6.6.dmg. When I double clicked on it a pop up message came on saying it cannot be opened!
I trying to keep my cool and reassure myself that all of this will be worked out and I hope VERY SOON.
P.S. Before I posted my first distress message on this post I did use the Print feature and save it as a PDF file. I created a D-size sheet for the page set up. I won't of the it will be properly printed on a D-size sheet till tomorrow.
Here is hoping for the best.
