Well I bit the bullet and upgraded to RealBand 2021. I'm now using the 64 bit version (it seems that the 32-version doesn't work anymore)
Anyway, the problem is fairly fundamental, yesterday I was happily moving tracks via the drop station to Ableton. This morning I drag the tracks across but no drop available. Ableton is exactly the same as yesterday but something is amiss. Any help please?

Thanks
