When I try to sign in to Media Center it brings an error that reads "strong
name validation failed for assembly C:\window\ehome\ehshell.exe'.  The file
may have been tempered with or it was partially signed but not fully signed
with the correct private key"

Does anyone have a recommendation what I can do to fix this so that I can
access Media Center.
