I noticed on the StarDock eula, the following statement:

An Individual User may:

1. Install, use and activate one (1) copy of the Software on up to five (5) unique personal computers simultaneously that are owned by you for your personal use.

1. For Software acquired from Stardock via an automatic recurring payment subscription method you may install, use and activate the Software on up to five (5) unique personal computers simultaneously for as long as your subscription remains active.

1. Software products associated with cancelled or expired subscriptions will be deactivated by Stardock and removed from Stardock product registration database until the expired subscription has been successfully re-activated.

2. The trial or free version of the Software is licensed to be used on one (1) computer.

Does that really apply to WindowBlinds???  I didn't see anything about that at the Store when buying it; I assumed (and believe it was reasonable to assume), that I could use one license indefinitely, as I did with previous licenses (I had previously used V3, V4, and V5).
