I have installed an evaluation copy of windows 2008 HPC Server on Sept 11, 2009. Then at Nov 18, 2009. It said the license has expired. [A problem ocurred when Windows tried to activate. Error Code 0xC004C00D]

Download the Windows HPC Server 2008 trial software and evaluate it free for 180 days.
Can one have this problem and know how to fix it?
