Most likely, it's an illegal copy of Prima involved. As with many flaws of illegal downloads, odd things crop up that don't exist in the official version. Prima is known to have such a problem. The problem is caused by her activation code, and while possible to avoid, it will require advanced information to circumvent. However, be aware not everyone within the Vocaloid fandom will take kindly to illegal versions of the Vocaloid software being brought up and some may criticize the use of a Vocaloid illegally.
