Hey I just updated my BB's OS this morning and i tried installing my Datavault through DM and instead of just installing the app, it said it was going to erase all data and reinstall it all. I dont want to do that, just install my Datavault. Is there a setting I need to change, it has never done this to me.

Blackberry 8310 AT&T 4.5.0.52

Blackberry Desktop Manager 4.5

What version is it trying to upgrade to? If you installed a newer OS on your PC, then just uninstall it. Actually - first restore the vendor.xml file you earlier renamed to even upgrade to version 4.5 and it won't bug you either

thanks lee, i feel like a real idiot now, i dont know why i didnt think of that!!
