Package won't load after v.7 upgrade

Hello,

A few days ago I was able to successfully load and use my own AddOn  
package using v.6 with Mac OSX.  My package is called "integExp.m",  
and I placed it in a folder I created called "Quantum", located at:

/Applications/Mathematica.app/AddOns/ExtraPackages/Quantum

To load the package, I used

Needs["Quantum`integExp`"]

It loaded and ran fine. However, I upgraded to v.7 yesterday, and now  
using Needs doesn't work, and I get the following nocont and notfound  
errors:

Needs["Quantum`integExp`"]
Needs::nocont: Context Quantum`integExp` was not created when Needs  
was evaluated.

?integExp
Information::notfound: Symbol integExp not found.

Did something change in v.7 regarding where to place AddOn packages?  
I've searched previous group posts and the Documentation center with  
no success.

Thanks is advance,
Porscha
