Sorry, we thought this was obvious. The components come with support subscriptions to help you install and configure them. It takes people time and resources to assist you. Customers cannot download the commercial components without the support subscription.
The subscription periods are for 90,180 and 360 days, during which time you get all the updates and help you need. Help is only through the ticket system of forum. The styling of the components is quite easy and you can easily integrate the layouts into the look and feel of your website. We will help you with this, but only if you submit a support ticket. Be aware that we do not offer 24 hour service, but we will generally get back to you within 24 hours, except for weekends and holidays. We want to help, just use the system and let us know what you need..
Also, your components do not expire when your subscription period is over. The components will work and are yours for ever. The only thing that happens is that you lose your support, unless you purchase another subscription. Most users will be fine with the 90 subscription as that will give you time to download install and debug the component before the subscription period is over.
