Demo expired on installation

I tried the server editon demo on a Windows Server 2003 server that has been running AVG for the last 2 or 3 years, but got the following message:

“Information about current update:
Last encountered error: The license key for this product is invalid or expired.”

Earlier, i think I saw a message that the demo expired in Dec. 2006

I’d like to try the product, but obviously this is not working.

Please advise,

Thanks,
