Just downloaded this product and installed on a clean install of DNN. After adding my first product to this cart, I get the following error after clicking on the product detail page: AssemblyVersion: 6.1.3 PortalID: 0 UserID: 1 UserName: host ActiveTabID: 88 ActiveTabName: Product Detail RawURL: /dotnetnuke/Default.aspx?tabid=88&ProductID=1 AbsoluteURL: /dotnetnuke/Default.aspx UserAgent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider ExceptionGUID: 87097bd8-e5f7-488a-ad70-29e3d0019af9 InnerException: Input string was not in a correct format.
