I have been trying to get trio to work, but it just wont. Here is what I did so far
I downloaded versions 1.4alpha5 of both trio and riot
extracted the arm to the audio reciver directory (replacing the original - I backed it up) then I extracted trio to d:\program files\trio
Next I edited the trio.xml file - followed the directions to a tee and re-checked it 4 times
next edited the batch file in the bin dir
started audioreciever - imported music, turned on the rio - got the trio spalsh screen, started trio.bat - rio now says connecting to server and thats where it all ends. I have included the etext from the dos screen thats running trio below.
PS - also tried to get it working with jreciever and no luck
(i am running pcanywhere on the same server if that makes a difference)
