If I buy OS X then convert to PC will I need to buy a new copy?

Hello all. I need to get software for my MacBook but I may convert back to PC in the somewhat near future. Will I then need to buy new software or will my key work for the PC version as well? Ty!!

Cubase is cross-platform. With the license on the USB-eLicenser, you can switch back and forth all you want.

Awesome. Thanks
