Every time you access the admin's page, you need to insert license. When you get to the admin's Control Panel, you see License is invalid in all the sections.


Parallels Pro Control Panel license is tied to a MAC-address. Therefore, when you change your network card, PPCP does not recognize the license as valid anymore.


Please rename /etc/appliance/.license/.LIC_file and /etc/appliance/.license/.MLK_file so that the license would be treated as a new one by PPCP:

# mv /etc/appliance/.license/.MLK_file /etc/appliance/.license/.MLK_file.bak
# mv /etc/appliance/.license/.LIC_file /etc/appliance/.license/.LIC_file.bak

After this, you  need to contact Sales Department and ask them to reset the license.
