Query: Couldn't use the solution

I couldn't use the solution because I didn't have the SYSTEM to use it with. When I bought it there was nothing about having a system ( which costs well over $100)before it could be used, or at least it wasn't obvious enough to stop me from buying it. So, I think you got me on this one. I didn't send it back because it would have cost me more than just throwing it away. Unhappy with the deal.John Ashley
