From this Monday, I found that if I attempt to (1) convert a Word document to a PDF using the Adobe add-in in Word, or (2) print a document (any document; pdf, docx, jpeg, webpage, etc. ), the program which I attempt to do these action will enter "not responding" state. Restarting and updating the system could not solve this problem, and I desperately need these functions. Please help me! Many thanks.
