I think the problem lies with the number of clicks you sent us: it’s just too few.
When ever you hear this from a program RUN RUN RUN … I have always held that such comments are an indicator of hit quotas!
If a program is converting at say 30:10 – EG 30% of clicks produce a download and 10% of those downloads produce a real account then by all means that ratio should remain constant regardless of the # of hits sent!
Considering that 30:10 ratio – If you were to send 1000 hits you would expect 300 downloads and about 30 joins. If you were to send just 100 hits you could STILL expect to get 3 players using that ratio. That 30:10 ratio has been quoted to me by numerous programs. One program in vegas even quoted me a 30:50 ratio, which has me skeptical, but none the less he claimed it and I am going to test it 
…
Again if a program is telling you to send more traffic and/or give us more or better exposure – do NOT hesitate to RUN in the opposite direction.
