I must be doing something wrong too.
I'm not too bothered as the communicator will supercede this software anyway
When you downloaded it did you move the file to your PilotClub folder Ernie? It wasn't in an installer package this time so you have to install it yourself.
The new version (2.4) has no added functionality over 2.3 but the coding is very different as some of the functions are now designed around the new Communicator client. Stefan hasn't given much away about Communicator but I suspect it will be a combined voice and text module. It may be with us quite soon.
