Hi again folks,
Solved the fatal exception error (post below) with a clean reinstall of Windows but now the my REL1000_0 is constantly showing as disconnecting and reconnecting.
I've tried three different USB cables and a couple of 12V 2A power adaptors but without luck.
The maddening thing is, very early on it did work - but now it's the same problem over and over.
Log attached. Any help greatly appreciated!
