I'm not quite sure which version it is, I installed it in March last year, and haven't updated it since, but every game I tried playing, worked, even newer games with various fixes, etc. The console is 320GB Slim version.
So far I tried deleting the PKDIR, PS3_EXTRA and the data installed by the PKG, that didn't work, gave me still the same error.
Then I found another PKG, installed it, and still the same error.
There doesn't seem any other solution besides downloading it one more time, from another place.
