on thursday night they posted new firmware for the remote (now 4.4) and also the extender (1.4). The issue where the remote won't connect with the extender is fixed.

The java errors when you have more than 4 devices being controlled by RF is still a problem. (To overcome this temporarily set device(s) you rarely use to being controlled by IR).

Their tech support out of Toronto is excellent (maybe you need to get past the first level folks).

The tech made me do some extreme things to update the firmware... if you have the connect problem and you can't resolve it by regular fw updating let me know here and I'll post the full instructions.
