I think you may be a bit mixed up between the WinCustomize and the Object Desktop subscriptions. I see you have purchased the WinCustomize subscription. This will allow you unlimited downloads of skinning/customization type items for a year. The benefits of this subscription can be seen here: https://www.wincustomize.com/subscribers.aspx?info The only thing with this is, you would need the applications to use many of the items on here.
This is where the Object Desktop subscription comes in. Object Desktop contains the entire suite of applications to customize/enhance your PC (WindowBlinds, RightClick, etc). More information can be found here: https://www.stardock.com/products/odnt/
You will probably want the Object Desktop subscription instead of or in addition to the WinCustomize subscription. If you would like to exchange, send an email request to sales@stardock.com and they will be able to accomodate you.
