When I add Entity Framework Designer, I'm getting an error message

Error Message An exception has been encountered. This may be caused by an extension.

You can get more information by examining the file 'C:\Users\The Gatwayinfoteh\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml'.

When I look at the log file, I find

System.ApplicationException: Unable to remove the collapsed region from outlining manager, which means there is an internal consistency issue. at Microsoft.VisualStudio.Text.Outlining.OutliningManager.ExpandInternal(ICollapsed collapsed) at Microsoft.VisualStudio.Text.Outlining.OutliningManager.UpdateAfterChange(NormalizedSnapshotSpanCollection changedSpans) at Microsoft.VisualStudio.Text.Outlining.OutliningManager.SourceTextChanged(Object sender, TextContentChangedEventArgs e) at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent[TArgs](Object sender, EventHandler`1 eventHandlers, TArgs args)

Can anyone see how to interpret this so that I can figure out the error?
