I have been unable to update the aviation and obstacle databases. I have a full Dynon setup and have been very pleased with how everything installed and works, but when attempting to update the aviation and obstacle databases with the latest version (May 21-June 17, 2020), the HDX doesn't recognize the file on my USB stick. I have tried two different sticks, both of which worked in the past. I have downloaded the file numerous times, and have tried formatting the sticks and then copying the file from my "Downloads" folder to the root directory of the sticks. The HDX still doesn't recognize that file. Any help would be appreciated.
