He is sending you the "lite" version of this:

http://www.native-instruments.com/#/en/products/producer/guitar-rig-5-pro/

It is "amp simulator" software that tries to sound like you have various different amps and effects. I have a previous version, it is pretty fun but not quite as nice as having the real amps and effects. It is worth what he paid, but not more.

You might not find it convenient for your setup, as you noted.

Hope that helps.
