I suspect your old version configurations are conflicting with the new installation. Perform these steps and then re-install the program.

Mac OS X Tiger/Leopard:

(Assuming you installed to Macintosh HD and your user name is USER)

1. Applications : Vyzex Pocket POD: Trash this application.

2. Macintosh HD : Library : Application Support : Psicraft : Vyzex Pocket POD: Trash this folder

3: USER : Library : Preferences : Sound Quest Preferences.ini : If Vyzex Instrument is your only Vyzex or Vyzor editor, then you can trash this. Otherwise open it with textedit, delete the text blocks with the headings containing Line 6 Pocket POD and then save the file on exit. This file is the software's answer to the Windows registry when running on Mac, incidentally.

4. USER : Library : Preferences : Psicraft : Vyzex Pocket POD: Trash this folder

5: USER : Documents : Psicraft : Vyzex Pocket POD: Enter this folder and trash only the Default.SQ9 file contained within. The other files in this folder (and subfolders) are your collection and any data files you may have created with the editor, so don't trash these if you value them at all.

Next, run the installer program again. The program should only allow itself to be installed on your root drive (and the root drive should have a relatively conventional name without slashed, colons or umlauts in it). Once the program is installed, try running it without the Pocket POD connected to ensure the previous crashing was not a consequence of USB port malfunction. Once the program has run successfully without PocketPOD connected, connect the Pocket POD to the USB port closest to you on the left side of the MacBook Pro as you face the screen, and run the program again.

Does this resolve your issue? Please let us know!
