upgrading software on Hobbywing 120A v2.1

[dobber]

Right, im not too sure what to do to be honest. Ive got the 2 in 1 program box and i want to put the most up to date software on esc.

What ive done so far is;
Installed the software from the disk provided and plugged in the program box. It says there is an update but it says failed to download.
The current software on the box is V1.07_110119

How do i get the latest software to download. What have i failed to do (probably something daft!) Should i have connected the esc up to the box at the same time?

Heyelp!
