Hey. I am having a problem with my logic. I just got a new macbook pro, running OS 10.4.8. I have Logic 7.0 (upgrading soon). The problem I a having is this. I used Logic 7.0 on my home computer, a dual 1.8 powermac g5, and everything worked perfectly. Now that I have installed logic on my Macbook Pro, I have tried to open songs that I made and recorded on the PowerMac. I get the error message "The file 'Pop Kit.exs" is not an EXS instrument file." or 'Jazz Kit', whichever one I happened to be using, and it's like that on all of my songs. If I try to record a new song, it doesn't find them either. It recognizes all exs files I recorded before, except for all drum kits. the bass guitar, keyboards, whatever else I recorded by midi works fine, except for the doggone drum kits. It's like Logic isn;t talking to garageband, which is where the sounds came from, they're just the standard included drum kits sounds. I'm about at my wit's end, can anyone help?? Thanks.
