Error occurs when deleting the sandbox...

[Unknown_User_893]

When I delete the sandbox, there is an error message and the sandbox folder under"Application Data" are only renamed as"delete_defaultbox_.....".

I tried to remove the whole folder, including the files inside, but unsuccessful. I even tried to use some software to remove it.

What can I do to delete the folder and the files inside? It seems to be locked by something unknown...><

Someone reported a similar problem, here, but it was never solved , i would suggest installing unlocker and seeing if something is locking the folder, and if so, see if unlocker can "unlock" the folder, if not, then use unlocker to delete the folder, when it says some thing like "unlocker cant delete the folder, would you like to delte it when you restart" (something like that) hit yes, then the folder will be deleted when you reboot.
