membership, not search friendly long URLs

I use your whmcs integration plugin.

When I found your website it was stated: 2 options were there: 9 dollars once payment or 19 for unlimited updates, support and so on. Now I see that you put my membership to pay every month but for what? I do not need to pay every month. Can you tell me how to stop this? It is not fare!

And now this system force me to write more. Another question is how to replace not search friendly long URLs with normal URLs? Nowhere it is described in your documentation. Maybe it is somewhere in the member area but if so than it is not fare again.
