reinstalling the combo update should keep all my software intact? Thanks again :)

Yes, if you reinstall the combo update all your data and software applications will stay intact.

Hey Gary, I tried both using a new user and installing the update you recommanded but none of it solved the problem... As a new user it worked at first but once logic started loading the AU (unit manager) the internet went off again. I'm no expert but it seems like when I lose connection of the USB mouse there's a peek in the disk. If I wait for about 5-10 seconds it reconnects again. As far as the internet, I have to quit logic and reconnect the USB wireless cable before I can connect again. Thanks again for your help, if anything else comes to mind please let me know, Danny

I'm lost for any other ideas. Except for maybe clean installing your Mac and starting from fresh again.
