Downgrading my OS-- will my license still work?

Hi there, After encountering unfixable problems using Yosemite and ProTools 11 on my computer, I'm downgrading to both ProTools 10, and to Mountain Lion. To do this will require wiping my harddrive.



I just want to make sure that this is not going to mess up my authorization. Do I need to deauthorize the software, or are there any other steps I need to take to be able to use it again on my fresh slate computer?



Here's all my particulars (not that I think they're relevant for this question...)



I’m having a strange, seemingly glitchy problem with my new ProTools set up. I’m using the mBox Pro, 3rd Generation, along with the ProTools 11.2.0. (Before this I was using a Digi 02 with protools 7 for about ten years, so I’m an experienced lay user.) My computer is an iMac (21.5 inch Mid 2010, 3.2 GHz Intel Core i3 Processor, 4 GB 1333 MHz DDR3 RAM, operating system is Yosemite.



My designated hard drive for recording is a GTech 2 TB drive, 7200 rpm, 64 mb cache. Because my computer has only one firewire port (800), I’ve followed instructions in these forums for how to daisychain my harddrive for optimal performance. My computer connects to the harddrive, (FW 800 - 800) which then connects to the mBox Pro.





Thanks so much for your help!
