midis

Hi …I recently transferred my cubaseLE from old to a new computer…Latest Windows .
in Windows 7, I was able to change sounds from a midi in to audio. Now in the new one I can choose and assign sounds but when I try to save it changes back to the original midi sound …won’t save the new assigned sound…Is there a setting I need to look for and where do I find it ?
Thank you for your help

Has anyone ever had a similar problem?
