This has been a reoccurring problem for me for about a year now. My UTAU program has horrible screeching and softness jumps throughout a song. I know for a fact it's not my UTAU herself because it happens with other UTAUs as well. And other people don't have any problems with my UTAU. I also have tried upgrading and redownloading UTAU like 6 times. Nothing.
Here is an example of her problem:
