Error message when I'm creating PDF plot in AutoCAD LT 2011

When I'm creating Adobe PDF.pc3 - plot in AutoCAD LT 2011 I'm getting error message on notepad:

%%[ ProductName: Distiller ]%%

%%[ Error: invalidfileaccess; OffendingCommand: showpage ]%%

%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

%%[ Warning: PostScript error. No PDF file produced. ] %%

Earlier plotting in PDF on my PC was OK. The above happens recently.  I reloaded my Adobe Acrobat X Pro including updates few times even using AdobeAcro Cleaner and also I reloaded my AutoCad LT 2011 program, but I'm getting the same Error message. I checked with Autodesk and they told me the problem is

with my Adobe Acrobat X Pro installation.

I think something is missing. I'm using the same programs and same operation system on my laptop and have no problem with printing in PDF.

On my PC and Laptop  I'm using Microsoft Windows 10 Pro Version 1511 and all other programs on my computer are working OK.

Please help
