My big beef here is that people who write and distribute software for the car player need to support their own distributions by supplying scripts or at least proper detailed instructions so that Linux newbies can install the thing. Leaving out important information like "chmod 755 the following files..." causes problems like the one above.
My website has been updated with instructions on how to change the permissions for the files uploaded to the Empeg. Said website has always stated that the software is in beta, and since this is the first time this problem with the instructions has been brought to my attention, it wasn't fixed until I saw this thread (then I fixed it, problem solved). This is not a commercial piece of software.
I agree we need a universal platform-independant installer, though. Whatever happened to that project?
