Hi I am unable to figure out how to upload a predasaur file to my new T-Rex 4.6 CAM. I am using a USB PCB loader card, which is detected by Windows 7 on com port 2 ok. I have tried dragon loader and DragonCrypt, both do not detect the USB loader card. I assume these 2 applications need serial port connections instead of USB. Any help would be greatly appreciated.
