I forgot to add products before I added languages.

I Get this error as soon as I click on localization icon and choose sv-se; (Input string was not in a correct format)

DotNetNuke.Services.Exceptions.PageLoadException: Input string was not in a correct format. ---> System.FormatException: Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Convert.ToInt32(String value) at Smith.DNN.Modules.BuyNow.AddProductLocalisation.ddlLanguage_SelectedIndexChanged(Object sender, EventArgs e) at System.Web.UI.WebControls.ListControl.OnSelectedIndexChanged(EventArgs e) at System.Web.UI.Page.RaiseChangedEvents() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

I have reinstalled dnn site twice and upgraded to 5.06.01 without any improvement. Have I missed something? Server is 2008R2 and SQL is 2008r2
