No Instrument Insert on Instrument tracks

[Bazbo]

Hi,

I am fairly new to PT. I have had my own system for about 4 weeks, consisting of:

MacBook Core Duo 2.0Ghz with 512 MB
Pro Tools Academic 7.3
M-Audio Ozone keyboard/interface
Old World Computing external drive.

When I have an instrument track, I cannot access any instrument plugins.

I click the little insert button, then pick multi-channel plug-in, and the next menu over looks like this:

Dynamics >
Reverb >
Delay >
Modulation >
Dither >
Sound Field>
Other >

The books, manuals, and the workstations at school all show an "Instruments" option in this menu, and that's how I have been using instruments. I have tried searching DUC and have not seen this mentioned anywhere. I have Expand! installed with the 1.0.1 upgrade, and I'd like to use it. What am I missing?
