[TERM]

I have a DVC2 128M which was bought last year but hasn't been used until now. I'm just setting up the lighting today.
I'm planning to use it stand alone with the 4 ports to select a scene and was just looking to see if you can select more than 4 with this model.
It was working fine and now has just packed up.
The power light is on.
The software recognises it and even loads the scenes from the memory.
The software crashes if you try to delete the memory or write to it.
The DMX is not working.
Firmware upgrade fails as the interface goes offline.

Any ideas???
