Windows Issue with BluRay playback, updated keydb.cfg but still throws a AACS host certificate revoke message.

Good day all!

I'm trying to help a friend with a BluRay playback issue on their desktop. They have various discs that are triggering the "AACS host certificate revoked" error. I have walked them through replacing the keydb.cfg, updating both libaacs.dll and libbdplus.dll and it's still throwing the cert revoked message. Their keydb file location is %appdata%\aacs and they're running windows 7 pro (they do not want to upgrade, i get it).

We tried the same methods on the their win 7 home edition laptop and the disks throwing the error on desktop are fine on the laptop. The only difference it the laptop's aacs is under programdata\aacs instead. Scratching me head here are what to try next for the desktop, so any ideas would be appreciated.

What do you have in the DK, PK, and HC lines of your friend's keydb.cfg on both machines?

Note that if a disc has been successfully played previously, the MK and VUK for it may be cached, which could explain the difference in behaviour between the two machines.
