I will give you a link to download the drivers.

Hey,

make sure you have removed the protective tape from the cartridge.

if you have your old cartridge and it works, and when you then again place this one in and you get the error, then the problem is the new cartridge.

please contact your dealer for a replacement.

Thanks and good luck.
