Did you do "Upload and save" after the time you got the flashing red LED? If you don't overwrite the old nodes configuration, nothing will change.
To explain this a bit further, the nodes configuration is stored on the SPI flash memory (the 8 legged 'Winbond' chip near pin 36). When the firmware starts up, it reads the stored configuration file from the SPI flash and tries to run it. Many years ago, the file format was different and incompatible with the current format, so the current firmware will basically crash when reading in the old format. Holding pin 40 high will skip reading the SPI flash and start with an empty configuration. You then need to "Upload and save" to write a configuration into the SPI flash with the new format.
If the red LED doesn't flash when you're holding pin 40 high on power-up, I can only assume it wasn't contacting very well? The pin labels are not related to the MCU pin numberings btw, they are just numbers I made up for iomixer.
