Has anyone ever come across the following error when downloading a run to computer via SD... "The Start Character was missing from the Cartridge. Please check the hardware configuration, cable and repeat the process starting at the download from the onboard computer." When I go to download, it shows the .ddf file there, but click on it and nothing happens.. Keep clicking and that error comes up. We have lost our last 5 runs of data due to this issue and no one seems to be able to understand the cause. Logging is triggered when engine RPM is above 1500, all the settings are as they have always been. The only difference is the logger has just come back from RacePak with an ignition timing fault. I have tried new SD cards, new car config, replaced half of our VNET cables still no avail. It also seems to be deleting files off the SD card.
