UTAU won't play any sound after I save a UST

Today I started making a UST from a midi, and I imported that, and started inserting lyrics and tuning. The voicebank I was using was working perfectly, even though I was using TIPS. However, once I saved the UST, whenever I press play (even after I clear the cache), nothing plays except for if I use resampler.dll, and it sounds ugly with a soft voiced utau (and the breaths are horrifying!). My computer already has Japanese locale, and i changed the comma to the dot in the Control Panel. What's going on?

 

I had the same problem!
Turns out you have to run UTAU as administrator, otherwise that happens.

 

Thank you! UTAU is finally working again
