I paid the $39.00 from tech support to get this fixed in Aug. 2011 and now it's back.
How did you get it fixed then? What was the solution?
Do you have any 3rd party plugin installed for Adobe Reader? If not, close all running instances of Adobe Reader and delete the entire folder at: C:\program Files\Adobe\Reader 10.0\Reader\plug_ins.
Now goto Control Panel > Programs and Features. Locate the entry for Adobe Reader X and chose to repair the installation.
If you do have a 3rd party plugin installed, try uninstalling them and see if the issue is related to the same. If it works, do let me know which plugins were causing the issue so that I can have a look.
Hopefully, this should fix things.
Your suggestions worked. Thank you for your help.
I followed your instructions and am now able to open my .pdf's without getting the error message.
I'm going to printout what I have in my "plug_ins" folder and compare it to what I have in it if this ever happens again.
Then I'll know what is causing the error.
Thank you againe for your assistance.
