Palm Tungsten|T sadness, and then happiness
I had to do a hard reset on my tungsten|T. After re-syncing on the mac, I'd get a message that said "Launch Error - The application cannot be launched because it is missing localization information" when trying to click on the 'home' icon.
After some googling, I found the answer. Credit goes to "blueztelecaster" at the palmzone.net forums.
Here's what you should do to fix the problem. FIx make sure that you've HotSynced, so that the information you had before this problem happended is stored on your computer. Then, do a Hard Reset, which means holding down the power button while pressing the reset button on the back. Then remove the Backup Folder from Users>Your Home Folder>Documents>Palm>Users>Your Palm User Name. Take the Backup Folder and put it on your desktop. Hotsync again and everything will be fixed, but you will have to install any extra programs that you have installed over time.
Another option was also given, if you happen to have filez installed:
I had FileZ on a memory card. I mapped a button to launch filez, and deleted the launcher.prc from the internal palm card. That fixed it as well, without doing the backup procedure.
Good to know.
