Liteon 5006 Macrovision hack failure

I bought a 5006 last month and followed the instructions to disable macrovision.
I downloaded the relevant firmware update from Liteon (as determined by my serial number) and the hack exe file.
I ran the hack file and obtained the following error message “…cannot find macrivision hex string…”. This is as far as I got.
Can anyone suggest what I am doing wrong or, have Liteon become too clever?

You cannot hack the current official firmware, you need to get old of an older firmware and hack that.
