What did you need to know about the basic? Did you call LinkPoint about the API integrattion? Our clients are usually on the API, but my programmers deal with the integration. I do have some source code that might be able to help you out for the API, but the Basic is really simple. Did you follow the link the in e-mail?
We went through the LinkPoint struggle as well. If it relates to hosting, I recommend using some billing software that supports the LinkPoint API such as ModernBill. Saves hours and hours of programming with stupid linkpoint. They should program it for us for the gateway fee they charge every month :-o
