I'm getting an error with Contour when I try to create a new pre-value source or datasources.  Originally there was a conflict with a custom macro property type called formPicker which prevented the contour macro property type from being added on install, and so was added manually.

[ArgumentException: ERROR CREATING CONTROL FOR NODETYPE: formdatasources]
   umbraco.cms.presentation.Create.Page_Load(Object sender, EventArgs e) in d:\TeamCity\buildAgent\work\7380c184e9fcd3ea\umbraco\presentation\umbraco\create.aspx.cs:45
   System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14

   umbraco.BasePages.BasePage.OnLoad(EventArgs e) in d:\TeamCity\buildAgent\work\7380c184e9fcd3ea\umbraco\businesslogic\BasePages\BasePage.cs:287
   System.Web.UI.Control.LoadRecursive() +50
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

Anyone see this before?  Should I just reinstall?

Thanks,
