After installing boxee media manager on Windows Vista, launching results in an error... bmm_tray.exe stopped working.

The event log is reporting an issue with QtCore4.dll:

Faulting application bmm_tray.exe, version, time stamp 0x4e3a9e5a, faulting module QtCore4.dll, version, time stamp 0x4d943253, exception code 0xc0000005, fault offset 0x0009abe0, process id 0x12d0, application start time 0x01cc56f448fa927f.

I've rebooted and re-installed. Any advice ?
