DAE: Can't find "DAE FOLDER" in system folder. (-9064)

I use a Yamaha MOTIF XF 8 with CU Base AI 5 and Logic Studio. I made a huge mistake and changed a prefrence in the AUDIO area and I cannot access the Prefreence Audio area now to change it back to the way it was. I noticed a previos thread that showed someone how to change it back but mine is not highlighted (prefreence or audio) so I cannot click on this area. Can anyone help me out here, would greatly appreciate it.
