same problem. I am logged in. "Touchless" says 'downloaded.' Using a 5-mo old MacPro OS 10.9.5, although it seems that the 'downloaded' status has to do w/the way your site is configured, as opposed to the system or browser it's running on. Tried to transfer apps from my old computer, but they came across corrupted & won't open. In addition, on my Account page, App Purchase History tab is completely empty, even though I'd previously downloaded 6 apps, including Touchless. Right now, my LeapMotion controller is useless for everything I'd been using it for. It's pretty common for someone to need to download an app more than once, either due to a crash/data loss, new computer, or additional computers. Why does the site even need to block users from downloading an app twice?
