Forum:Why do all the English UTAUloids I downloaded not work?

I downloaded various English utau voicebanks, Teto, and "UTAU Ver 0.4.17". I was having touble with Teto because I don't know what lyrics to put in which would work, because when I pressed play, there was no sound. There a menu with the sounds Teto can make, and that was working, but they were all labled as weird symbols. (not a language)

As for the English voicebanks, well, UTAU didn't like their file type or something.. Because it didn't accept any of them. ;-;

Please help! I'm really really stuck!!
