How do I downgrade my MacBook Pro Safely?

[Bloody.Trust]

Yep, I'm asking for help yet again... Anyways! So... since Feral-Heart doesn't seem to work for OS X Mountain Lion, I was wondering how I can downgrade my MacBook Pro safely. I don't want to have any of my data lost, or have my computer run slower. If anyone knows how to downgrade my MacBook Pro safely and for free, I'd really like the help. I'd like to get back to my role-plays as soon as possible. Thanks.

You could try what's mentioned here:

Make sure you backup your files before you actually attempt anything that might cause errors.

There's a new FH download in the Mac thread; I don't think it's up in official downloads yet, but it uses the updated version of wineskin that works with Mountain Lion.

(My sympathies. Same thing happened to me)
