Hi I’ve been using Adobe Acrobat 11.0 version for a while and am facing following issues;
Can you please elaborate more about your issue along with the screenshot of the 1st error messages?
Also let me know the exact dot version of Acrobat XI & OS installed on your computer?
2nd Error occurs due to security implemented on the PDF document. It encrypts the text on the PDF so that I can not be copy & pasted.
