I'm having problems with Ruko and a UST

[Ruko4Ever]

Okay, I'm new to UTAU and I need help. So, I downloaded a UST of "Tell Your World" and I'm trying to get Ruko to sing it, but when I try, it says "invalid choice 1 option" or something like that. What am I doing wrong?

If the box says "Invalid Tool 1 setting" then perhaps clicking on the "Initialize Tools" button in the bottom corner of the Project Configuration window should fix it.

Okay, I'll try that.
