#4 Cant open my existing 1.x database

[Net Nut]

I had trouble with my existing database not opening when I upgraded ikeepass to 2.0 (all the entries were 90% empty). so I deleted the database from the phone and tried to redownload, and then the ikeepass would crash after launching every time. Do I need to convert my ikeepass database to a new format now, or should the old one work? should I uninstall and reinstall the app to get around the current state of the app?
Thanks in advance for your help.
