When I open a project in RealBand, as I've done in the past, and specify a new Realtrack (either over an existing Realtrack, or in a blank audio track), and click OK to generate, I now am getting this message:

"Wave instructions to wavfile failed, likely due to failure in Beatmap stretcher."

Which is not very helpful, as I have not knowingly used the Beatmap strtecher, much less messed with it, asked for it, or even heard of it. The online help doesn't really enlighten.

Previously this problem didn't arise, I could generate up to 7 new Realtrack multiriffs using this method; now I can't generate even a single basic RealTrack.

I'd be really grateful for any help. I'm sort of stuck here, as BIAB can render, but can neither create multiriffs or, suddenly (as I've just posted in the BIAB forum) export anything as wav files.
