Bug: Proclaim crashes at startup

Installed latest version of Proclaim on Windows Vista, Standard User account for projecting during church services.
Logged in, synced successfully, tested On Air - all good.
Came back days later, started Proclaim, crashed as I attempted to log in.
Uninstalled Proclaim using Control Panel.
Reinstalled Proclaim from the website. Logged in and all fine.
Restarted the computer, logged into user account, started Proclaim. It remembered my user account and logged in. Started syncing and crashed.
This is consistent behaviour on this PC. Uninstall, Install (all good), restart computer, crash. May be worth noting that I get the same behaviour on an Admin account. We really can't use this if it is this unreliable.
OS: Windows Vista Home Premium Service Pack 2
