I find difficult to understand with Line6 products is the overlap of the features with your software. 
For example, since buying my Line6 Guitar port, I have loaded onto my P.C. the following; GuitarPort Online (from Red Box), Riffworks (cost $99,99), Line 6 Monkey, Gearbox, Riffworks Line 6 Edition (Would not accept the $29,99 upgtrade licence key) I am really not sure which product to use as, apart from the Line6 Monkey, they all seem to do the same thing! 
There is an absence of clear consice instructions to instruct what product to buy when you purchase the Guitar Port., or which products do what. The Line6 Monkey does not show when similar products are installed and that if you have one piece of software you do not need the other. To most people, this is very confusing. This maybe smart marketing to have people doubling up on software, but confuses customers.Can someone explain or offer a solution? 
Thanks.
