It sounds like your work-around solves the issue.
I got the prc100.jar file off the piano, and I was able to make a shortcut to the javaw.exe file, but I can't figure out what to do after that.
Where do I enter:
-cp prc100.jar gui.prc100 -h=192.168.0.6 -p=3191 webremote -w=31910
(I will change the h=xxx.x.x to my piano's address)
And what does it mean to create a "start" in default directory?
Thanks again for your help!
