Cannot assign Plesk license key. When trying to upload I see the error:
tail -fn0 /usr/local/psa/admin/logs/panel.log 2014-01-08T15:43:16-05:00 ERR (3) [panel]: Invalid key: Unknown key format: 0: key_upload.php:100
Corrupted license key.
Make sure you are uploading the key like PLSK.00000000.0000.zip.
If the issue with license persist contact you account or sales maanger on reissueing the key.
