Cannot burn a dvd at the end of process. system propose to reactivate and request to send my serial number to adobe site to get back a key number. But there is no link possible to get the key. Already ask adobe help, they sugest to install PPRO 2.0 with a specific serial number. The file .zip downloaded, an error message number 1311 stop the installation process , looking for a file not existing on my PC. Recall Adobe help, they suggest to put my issue on this forum.
