Variaudio

Hi, I have version 5 but Variaudio seems to have developed a fault. Although it will perform normally, snaps to correct note, shows percentages etc, when I play it back it has not changed from the original. I could relaunch Cubase using the driver but I fear it may not accept it and I might lose Cubase altogether. If I could get Variaudio to work I’d be happy with V5, and I’d relaunch Cubase if I was sure it wouldn’t ask for security info eg passwords I no longer have. Thanks.
