Have you tried re-licensing the software (under the "Tools" menu)?  That should fix it.

If that does not fix it, reboot the computer, update the software, and re-license again.

If that does not fix it, confirm that your printer is working correctly.

If none of that works, you will probably need to contact Customer Support.
