Upgraded from version 1.0.0 of TinyMCE to 2.7.1 after upgrading to Episerver 11.10.6. Have the same issue when i use TinyMCE version 2.6.1.

I get a warning saying "Failed to load plugin url: http://mysite.local/Episerver/EPiServer.Cms.TinyMce/2.7.1/ClientResources/tinymce/langs/sv-se.js" I have confirmed that the file exists. 
I get the same warning if i change the UiCulture to eg. "da", it wont load that file either.

When entering the adress in the browser i get the following exception:

Exception information:
Exception type: StructureMapConfigurationException
Exception message: No default Instance is registered and cannot be automatically determined for type 'EPiServer.Cms.TinyMce.Core.Internal.IResourceResolver'

There is no configuration specified for EPiServer.Cms.TinyMce.Core.Internal.IResourceResolver

1.) new ResourceResolverController(*Default of IResourceResolver*)
2.) EPiServer.Cms.TinyMce.Controllers.Internal.ResourceResolverController
3.) Instance of EPiServer.Cms.TinyMce.Controllers.Internal.ResourceResolverController
4.) Container.GetInstance(EPiServer.Cms.TinyMce.Controllers.Internal.ResourceResolverController)

Does anyone have any idéa of what im doing wrong?
