hi everyone, two questions for ya: 1) I just got a Jampack but it refuses to install. It says I need GarageBand. The problem is: I already have GarageBand and it works fine. Does anyone know what I can do about that? I'm working with iLife 05 here. 2) I also just got a keyboard- Yamaha YPT 400 to be exact. It came with an installation CD, but the driver is a .exe file- Windows only? The lady at the store said it works with Macs. I plug it in, and I used the MIDI setup and it doesn't even register. I found a suitable driver (http://music.yamaha.com/products/downloads.html?productId=1212) but that, like my previous question, refuses to install. This time though, it doesn't even say why. Does anyone know what's going on? Thanks very much for your time.
