Uploading to ev3 doesn't work

[DomeD13]

Hi there,

If I try to upload my programm on my USB-connected EV3, the upload gets stuck after around 20%.

Output in the Window "Uploading to EV3..." is:

Preprocessing start.lms [DONE]
Generating rbf: C:\Users\john\AppData\Local\Temp\ev3starter5161276984488606014

Then it gets stuck.

I'm using latest Eclipse and latest EV3 Firmeware 1.10.
I can ping the EV3 and the Lego Software also recognizes the EV3.

Any hints for me?
