It is the buyer’s responsibility to check compatibility of an item before purchase. Program version and file type needed are listed on every file page. Unfortunately the WPBay Marketplace cannot offer a refund on purchased files that work correctly. However, if you have purchased an item and it does not work as described or is faulty, please contact support and tell them which file you purchased and exactly what the problem has been with the item. The item will be investigated, and if it is found to be faulty or not working as described it will either be fixed or a refund will be offered.
