Von, your problem might be that you need to use the 'External ASPI Interface'. The recommended one is Nero wnaspi32.dll. Just download it into your EAC folder, start EAC and go to EAC Options > Interface. Select 'Installed external ASPI interface', select OK, etc etc then restart EAC.

rainman, your problem is probably fixable if we had a bit more information. Do you shut down EAC after you rip and before you try using Flac Frontend?
