I installed an update to 2.2. Didn't like it so I reverted back using a Nandroid backup. Now I can't download anything from the Market. It just starts up and says "Starting Download" but does nothing beyond that any ideas how to fix this? EDIT: FIXED!! By following instructions online. I did a factory reset and re-synced into my Google account. Then I used my Nandroid backup and then Market worked.
