Hi,

I'm sure not to be the only one with this issue.
PEP gives me the error, when trying to download to the TSU:

Communication with the Pronto failed during download. Please check the connection and retry. (Error: C7, Copy)

I use:
TSU9400 (I got 2 of them, same error on both)
Windows 10 on 2 different PCs (same error on both PCs)
PEP 1.1 (indepenent which version, actually I use 1.1, but tested with the other versions as well)

I tested:
different USG ports, USB settings, running PEP as admin, in compatibility mode, etc.

In the past it worked with the same devices and config files.

Looking for help....
Rainer
