So the player tab appears, but when you select it nothing happens? Please send me the contents of the java console (via coffee mug in your system tray) and a screen shot of what you're seeing.

As for the "too many parameters" thing - I don't think it's causing your current problem - but it does explain your previous one. To fix it, enclose %TRIO_HOME% in double quotes as follows:

cd "%TRIO_HOME%"

THis isn't required on my win2k set up - what version of windows are you running?

Cheers
