IsolatedStorageException - "Initialization Failed"

I got this IsolatedStorageException - message: "Initialization Failed" - when using Enterprise Library. The line giving the error is in StorageAccessor.Silverlight.cs
   = IsolatedStorageFile.GetUserStoreForApplication();
I've gotten this error before in other circumstances, and usually occur right after I delete the Isolated Storage for a particular URL and reopen the app.

Tried rebooting, recompiling, reinstalling Silverlight runtime. Finally what worked was deleting this folder: C:\Users\User.Name\AppData\LocalLow\Microsoft\Silverlight

Apparently there is some corrupted state left over in there. I also noted that around this time I was unable to delete other app stores.
