Use the device option to completely shut down both GC and DV (double click the home key, when icons appear at the bottom, hold the icon til the red x appears and select the x). Then, go back to Game Center and signout of the account that shows. Then try to re-enter your original name. If that doesn't work, I think you will need to contact iTunes support.

If you do get logged back in, your DV should open fine. If it asks you about restoring a local park or GC park, select the GC park.
