Same happened for me. Any solution?

Skooter,

I first tried to download, upload the .lic file manually - this did not work despite me restarting IIS, logging out  and logging in, etc.

Go int the file located here:/umbraco/plugins/umbracocontour/formsdashboard.ascx and remove the scriptmanager tag at near the top of the page. This allowed the page to load correctly and then allowed Contour to license itself.

Hope this helps you.

Jamie

Thanks a lot Jamie! :) 

Update to the above: Just purchased and downloaded 3.0.19. After install, I see that this is still happening despite a new release:

Could not load control: '/umbraco/plugins/umbracocontour/formsdashboard.ascx'. 
Error message: System.InvalidOperationException: Only one instance of a ScriptManager can be added to the page. at System.Web.UI.ScriptManager.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.AddedControl(Control control, Int32 index) at System.Web.UI.ControlCollection.Add(Control child) at umbraco.cms.presentation.dashboard.OnInit(EventArgs e

After resolving this by removing the extra ScriptManager, I tried to retrieve my licence file. After sucessfully seeing the list of licences after a sucessfull login, I then clicked on the correct licence only to see this:

The license could not be retrieved

You must download it from umbraco.org manually
