Hi - the Odytron Patches should be a .eep file, not .hex, so you shouldn't have been able to load this as firmware (it'll only upload .hex files, not .eep)
What happens if you upload a different firmware? Does the software upload OK and all is back to normal? If it doesn't upload, click the "show console" box in Easy Uploader and copy and paste the text here, so I can see what happens. thanks
