I am posting this thread here as I couldn't find a satisfactory solution at the Propellerheads forum. I currently own Reason 3.0.4. When I install Refill Packer 3, I get an error meassage when I try to load it 'uknown error occured', then the app fails and closes down. When I install refill packer 2.5, it loads up normally but fails to create the refill 'Bad Format' error even though I am trying to create a refill with only two wavs. Has anyone had the same problem?
