HELP! LG Optimus V

[Electriic_]

I updated to the latest version of Ice cream Sandwich, everything went well, I rebooted my phone and when I tried to open the Market it said. "You must add an account to the device to continue. Do you want to add one?" When I choose, "Yes" It closes and nothing happens.

How can I fix this?
