For 'Reason' if you get the message "Failed to Open MIDI Support Library"

I tried to open Reason 3.0.5 with an MBox 2 on my new MacBook Pro (Leopard) and I got this message: 'Failed to Open MIDI Support Library.' When I went to my 'Audio-MIDI' setup on my Mac, nothing loaded properly...

I found the solution to this problem after looking around online, and figured other people might be having the same problem, so here it is...

First, create a new folder on your computer desktop and call it "Old MIDI Drivers" (or something similar), then go to Macintosh HD>library>audio>midi drivers, and move all the drivers (that you don't plan on using) from that folder into your "Old MIDI Driver" folder on your desktop. For example, I moved all the drivers out except for my MBox 2 driver.
After you do this, you may have to restart your comp. (I didn't) and Reason should run.

Hope this helps...
