Seem to be unable to transmit?

Hi guys,

First of all; Robert; thanks for a REALLY nice plugin from a fellow Dutchie
However, while being able to receive signals perfectly (and fast!), I seem to be unable to transmit to my old-style KAKU (or ARC, which seem to be the same) switches. Or -maybe more apropriate- can't seem to find how to.
Can someone point me in a direction?

Hi,
Are you sure you are telling indigo to transmit a valid code?

Guys,

Robert helped me through TeamViewer last night. Turned out I had selected the wrong ARC device type... Stupid me!
