"no more free clusters"

i'm getting that message from reaper. What does it mean? this just started happening as i was loading a multi-track template i've been using for jamstix

probably: out of disk space if your drive doesn't seem to be full, run a disk scan on it, might have a dodgy free-space count.

It means you have to pay for the clusters now. joking... I apologise... what dub said above

Clusters...those are those superduper yummy things in honey bunches of oats right?

It is jamstix thx!
