I'm not sure if any of you use Ascendo Datavault on your iPhone or not. Mine was working fine until I upgraded my Mac to Lion. The first time I tried to do a wifi sync, all the data became corrupt. After downgrading back to Snow Leopard (don't ask), I was able to recover the datavault data from an auto-backup. However, that one sync I did somehow corrupted something on the iPhone, since I can't boot up Datavault for iphone anymore. When I click on the app, it asks for a password as usual. No matter what password I enter, correct or incorrect, the app just exits. Since I can't get into the software, I have no way of syncing it to the Mac and fixing the data on there, or even using the software for that matter. I deleted the app, re-booted the iPhone, and redownloaded the app from the app store. Makes no difference, I still can't get into it. I'm assuming when you delete the app, some data files are not being erased, contrary to what you think should happen. When I re-install the app, it uses the old corrupt datafiles, and prevents boot up? This is all just guess work on my part. Does anyone know how to clear all data associated with the datavault software on the iPhone? I'm trying to work with the software tech support guys but so far they've not been too helpful.
