Licence invalid?

I have installed Avast 4 Server onto my terminal server. Licence expires next year (May 30, 2007), however I get an error message that says the license key is invalid or expired. Won’t update. Please help my terminal server is unprotected.

Please post the last (say) 50 lines from the file \setup\setup.log

Thanks

I reinstalled it and it seems to be okay now. Thanks,
