I think that Caramdir's comment is correct. Can you take a look at your profiles again now and see if there's anything still wrong? I'm seeing the same information here, at the main site, and at SO.
Okay, the names fooled me. Apologies.
There's not a lot that I can see to do from this end as we have no access to the SO user account stuff. Are you absolutely sure that you used the same openid on both systems? If you used a different one on SO, try setting up a new account here with the same openid as the SO and then I (or one of the other mods) can merge them. Or, as the account here hasn't done anything yet, I can delete or destroy it (not sure what the difference is) and you can start again and see if it works.
But if it needs anything that actually involves SO then you need to mention this on meta.SO. We only have access to our user tables, so can't force an association with an SO account (at least, as far as I can see from the tools. The only one that I don't understand that might help is "clear sessions" but as I don't know what it does, I'm reluctant to try in case it's dire.).
