We want to encourage everyone to use the subscription model. Why would you continue to own? The only answer would be if you didn't intend to update everything. We wanted to price the subscription model at a level where it would benefit everyone.
I know it is easier to look at the next guy who purchases and be jealous that his/her benefit from this program might be greater than yours, but think about it and realize that this program is either beneficial for you too, or has no impact on your purchase. The reality is this program can help everyone.
Some poeple don't like to feel "on the hook" and forced into a subscription, so we want to accomodate those as well. Some may want to maintain an existing site and have the tools they used but won't really want to upgrade at all, so the subscription model won't make sense to them.
We should come out with something new just about every month, so if you want to own and update everything the subscription should give you a significant discount whether you own everything already or not.
The sign up fee is realy only to prevent people from signing up for one month a year, getting all of the updates, and unsubscribing. That is why we are willing to waive it for super suite customers the first time, but not if you cancel and want to sign up again. That is why you have to call or contact sales since our web site was not set up for one time discounts on subscriptions.
We will be working on a solution to improve the installation and update process soon, but for now the installation and update process for the library is just like the super suite, and you should uninstall any previous versions before installing the newer one.
