I am facing issue creating a package for ListX modules used in our DNN sites.

Current DNN version is 7.4.2.

While trying to build a package for existing ListX components nothing happens. Logs shows following exception

2016-05-02 18:28:06,947 [Thread:15][ERROR] DotNetNuke.Services.Exceptions.Exceptions - ~/Default.aspx?tabid=55&error=Method+not+found%3a+%27DotNetNuke.UI.Skins.SkinInfo+DotNetNuke.UI.Skins.SkinController.GetSkin(System.String%2c+Int32%2c+DotNetNuke.UI.Skins.SkinType)%27. System.MissingMethodException: Method not found: 'DotNetNuke.UI.Skins.SkinInfo DotNetNuke.UI.Skins.SkinController.GetSkin(System.String, Int32, DotNetNuke.UI.Skins.SkinType)'. at Bi4ce.Modules.xList.Installer.lnkPackager_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.LinkButton.OnClick(EventArgs e) at System.Web.UI.WebControls.LinkButton.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

It seems the DotNetNuke.UI.Skins.SkinController.GetSkin() method is depreceated or no longer supported, can you suggest any workarounds for this. Any help would be much appreciated.
