Virus B banks A/B blank on startup

  • Turned the B on today and was faced with a series of messages about reloading factory presets into banks A and B which were now empty.

    This worked fine and banks A and B were back, minus my custom sounds of course....

    Got the message again later. Repeat and banks A/B are back again, but this is going to be an issue going forward if it continues.

    Anyone else seen this and got any advice?

    Thanks : )
