For me Adobe Acrobat 11.0 is the most user-friendly program. But today application has let me failed, one of the working file is not open and appeared an error - there was an error in opening the document, read the problem.
Opened a couple of other files, everything is fine with them.

Tell me how to be?

Can you right click on the document - select Properties and then see if there's a previous version ?

I have tried this methods couple hours ago, but it can't solve the issue.

Adobe Reader has moved on from using the numbered versions such as you have and is now using Adobe Reader DC.

It would be up to you if you wanted to update - www.adobe.com

If the file has for some reason become corrupt and a previous version isn't available, then this program may help to repair it.

I've never had occasion to repair any PDF files, so can't vouch for this program but create a restore point first before using it.

Read some themes on adobe forums, open .pdf file in other versions of Adobe Acrobat, by condition nothing of these isn't work, you may apply PDF Open File Tool, check it out https://www.openfiletool.com/pdfopen.html
