Wilco A380 FS2004

I am installing the FS2004 version from the CD (A380V2) which includes both the FSX and the FS2004 versions. The FS2004 version has the install exec as v1.4. On the pdestal in 2d view, there are no clickspots on the transponder which will allow changing of the transponder digits. There is an area to the left of the transponder window where you are supposed to click the toggle upward to activate the transonder. How do you change the transponder code?. I have been trying to get a response from Wilco support since late October. Does anyone have this installed and working or can offer any support?ThanksDom
