Forum:"Invalid voice setting"...

So, everyone on this forum is probably dead, but I'm going to cry for help here anyways. So, I downloaded Nizimine Kakoi's voicebank, and all of the sounds in her folder look like weird english letters. I can add her by going to Option then Bank Regist and clicking any of the syllables, but when I try to switch her out with Defoko in Project Property, it says "Invalid voice setting". I would appreciate any help, if anybody is still on here. Thank you so much!
