ITunes :: Can't Access Its Library On A Shared Drive

Here is my problem: I want to access my iTunes library from a shared drive.

Here is my equipment:

1. Imac running iTunes 10.6

2. 1 week old Macbook Air running iTunes 10.6

3. 1 Timecapsule that is 1 day old, bought with the express purpose of putting my extensive iTunes library on it, and was assure I would be able to stream it.

4. An Airport express hooked to my stereo.

The concept was that the Air doesn't really have the capability to hold all my music, but I want to use it as a "remote" to select songs through iTunes and play them on my stereo. I did NOT want to leave my iMac on at all times and do homes haring that way.Therefore, I followed intructions fonund else where and moved my iTunes library from my iMac to the newly installed shared drive on the Time Capsule.I went into iTunes on the Air selected preferences, advanced, and changed the location of the Air's iTunes library to that of the one on the Time Capsule. It sees all the music. I close preferences.
