Do not use Emplode version 2.10. Do not use Empeg firmware version 3 alpha. The new error you are getting is because you switched to the alpha versions... Don't do that.

Put them both back to the known-good version 2 stuff you had before; that should have been fine. Player firmware: Either version 2.00 final or Version 2 beta 13 from here. Emplode: Version 2.00 final. Use only those.
