Media Revocation and Renewel your computer must restart

I have a Napster service ..and when I play the files after about
maybe 25-30 files I start getting a popup saying Media Revocation and Renewel
"You must restart the machine to continue content processing"
which I did..then it works for another magical number and continues again
I updated Microsoft Security Component Upgrade
This issue seems to be new to windows 7
as I never had this in Xp using the same Napster service and the media played fine.
I have not been able to find a solution to end this loop of Media Revocation and Renewel Error Message.
Any help would be appreciated

hello Profdlp
Thank you for your reply. I already followed this procedure from that page ,did the update components from that site all with no luck
umm maybe I miss something< I even went as far as uninstalling my mouse (logitech)nothing else on there do I have.

I will try this however I do think I ran it as admin..but now I'm not sure.
I have tried so many thing's now but that being a basic I think I would have...
ackkk it's painful too the program runs sooooooooooooo slow in 7
almost 3 hours to convert the 3o songs...thats the magical number

ohhh sorry...thank you
