well in the license it says "In the event a Buyer is not satisfied with the product a refund may be issued. Issuing refunds is at the discretion of the Artist and / or the Renderosity MarketPlace staff. Refunds will be issued only after the Buyer has worked with the Artist to fix the problem. When a refund is issued, the Buyer is responsible for deleting all files using the product and may not distribute the product." So yes, get with the vendor first, who I am sure will work with you, but if it can't be settled then go back to Rosity. Like Tygercub says, the vendors here are really cool.

In a world filled with causes for worry and anxiety...
we need the peace of God standing guard over our hearts and minds.
