Printing protected PDF files

Once every year, I need to print a protected PDF-file. Of course I forget what I did in between. The main problem is that you can't print a protected file from the Adobe Reader even if you have the password. They want you to buy the full Adobe product

2. Unzip it and go to the bin directory. Run: Decrypt.exe . And the file is printable!!
