BASS.DLL doesn’t matter since it’s a newer version so it’s better. The newer version is needed for the 2.2.2.0 client.
The graal.sig shouldn’t matter since the client is cracked. Try download a Graal v2.1.7.1-only package and replace the Graal 2.1.7.1.exe in the Graal 2.1 + 2.2 with the one from the 2.1.7.1-only package. This should work. If it still wants graal.sig, take that from the 2.1.7.1-only package aswell.
I was testing that new client today and got three different errors. Just putting the 2.2.2.0.exe from Agret’s rar into my 2.17 folder and running it would leave it running in my taskman but it wouldn’t come up. Unraring the whole package and running 2.2.2.0 made Graal bitch about the exe being modified. Messing with the dll’s got me the outdated bass.dll error.
