Hello,
Please make sure you have all updates installed. (If you don't know how to use the update function yet, here's a short tutorial including a screenshot:

Restore the files you deleted with Spybot - Search & Destroy: Run Spybot - Search & Destroy, select 'Spybot - Search & Destroy' --> 'Recovery' from the left bar and restore all the files and entries, which are in association with the item that should be restored. For your problem, it is especially important to have the tools update installed. Here is the direct download link for the tools update:

After following these steps please try again. Be sure that all the Explorer windows are closed. Maybe you will have to restart your computer.
Best regards
Sandra
