Have you repaired permissions? Have you checked to see if the EOS software has an update.
At the desktop press the option/alt key (while keeping it depressed) take the mouse and click on GO and click on Library (you can let go of the depressed option/alt key).
Scroll to Preferences and open. Look for the EOS plist file and move it to the desktop.
Now try it again.
Also check this site http://appleusergroupresources.com and look to see if there is a user group nearby. There may be someone in your locale that can help you.
