Yes, I was able to extract the files properly.  Also, this product has sold over 270 copies in a 1 year span of being active and have not had any issues.

Yes, Rpublishing is the content creator for Renderosity, however, the marketplace and Rpublishing are two seperate entities run by different people on our staff.  I am going to go ahead and contact them on your behalf and explain to them what is happening and see if they can't help you out in some way.

Thanks,
