Extension Manager 2.1 for Mac crashes when trying to install any extension

[reminoremi]

Hi,

I have the Adobe Extension Manager 2.1 installed on a Mac running Mac OS X 10.5.6.  I updated all the latest Adobe and Apple software.

I tried to install MXP files for Adobe AIR, jQuery, and Drupal, but doing so crashes the Extension Manager.  I tried uninstalling it using the Photoshop installer (which is what installed the Manager initially), but this didn't help.

The Manager also crashes when I try to open the Help > About the dialogue, both from the main window and from the menu bar.

Can anyone help me with this?  Thanks in advance!

Forgot to mention that I'm using Photoshop CS4 and Dreamweaver CS4.

Reading the thread linked below resolved my problem.  I only had to uninstall Safari 4 Beta before I could use the Extension Manager.
