I installed tRio version 0.1.4 and everything is working well (JRec, tRio, RioReceiver), but I can't access the tRio web page.

Huh?

I bookmarked:
http://raid0:8090/trio-applet.htm (this is the address to my web interface)

Where "raid0" is the computer that trio is located. Open a web browser, copy the above http except replace raid0 with the name of the computer that is running trio and it should work.
