For some reason, when I try to enter the new 30-trial password, it doesn't go through. I tried to redownload Utau Synth, but when I click on the download for Mac link, it says 402 Forbidden and I'm unable to download. I know the code is correct, and that I'm selecting the whole thing. What's wrong, why is this happening, and most importantly how can I fix this? I need to use Utau!
