Switching from Mac to PC

I purchased the Mac version of aTV and successfully used it. I am in the process of upgrading to v4.0 as I just upgraded ATV to v3.0. Since I last download aTV however, I’ve moved from a Mac to a PC (someone else is using the Mac). Is there a way to continue downloading upgrades to aTV, even though it is the Mac version, and install it on a Windows formatted flash drive and then on the ATV? If not, is there a way to switch to the Windows version so I can successfully continue getting and using the upgraded versions paid for?
