Interactive WhiteboardsActivInspire & MacBook Airs

We have Inspire professional v. 1.8.64868. When I check for updates, it tells me I have the latest version. When I use your link, it takes me to the download site to purchase software. We have 100 series Promethean Boards. We have bought rights to the Professional version just months ago but I am unsure if I can use the same key to download this version 2.2. The MacBook Airs  were purchased in 2013 and have 3.0 usb ports. Any further input or would you suggest a tech support call still?

Thank you!
