Unfortunately, the information provided does not indicate whether the SignX Media Editor program has a specific version that supports LED-403 SX (IP12 24x80 RG). It appears that the user encountered a limitation with the 2.08 version they installed, which only had a 24x160 option. They may need to reach out to the program's support or consult the documentation to check if there is a version compatible with their LED-403 SX (IP12 24x80 RG) configuration.
