Error on Updater 7.3 to 7.4 GID=2020

[abickle]

I get this error when running the updater from plesk 7.3 to 7.4
Any body know what this means..
I cant get this Virtual Server to update.


===> Checking for the necessary system accounts
Checking for the system groups and users necessary for Qmail...
Checking for the group 'nofiles'...

ERROR: It seems there is a group with GID=2020
in this system, but Plesk needs the same GID
for its operation.
Sorry, but this situation is not properly handled yet.
Please, contact [email protected]
