Tassy and Hal, ya should NOT be so dissapointed the problem does not sit in the project itself but the exposure of the project.
Meaning not enough eye balls are seeing it
Good luck and get more eyeballs on this.
For example and I am serious take that 20 bucks and 20 or so sales and buy a slot on The Hun. It will yield more exposure and repeat this on a few different hi profile portals.
I think it would be a sound investment to promote the project where more eyes will see it.
