Problems with Public Folders in Exchange 2010

Question

Last month I upgraded my servers from 2000 to 2010. The route I took for exchange was 2000 -> 2003 -> 2010. Everything went fairly smooth and I have had no real problems until this week. (I have uninstalled the older exchange servers.) I have been
trying to clean out some of the remnants that have been left over from the older servers (for whatever reason the uninstall did not remove the information on the new server). I used ASDI edit to remove some old information that was pointing to the old exchange
server (First Administration Group I think it was called).
After that I upgraded to SP1 and Rollup 1. The Public folder database no longer appears under Organization Configuration, Mailbox. I am not sure if it was there after my deletion or not, so I am unsure if the problem is caused by my deletions or the upgrade.
I followed the instructions found here, http://technet.microsoft.com/en-us/library/bb727370%28EXCHG.80,printer%29.aspx . The CN=Public folders was found in CN=Folder Hierarchies. However
msExchOwningPFTree is greyed out, so I cannot update it. I have tried to delete it and remake it, same thing.
I also get the following events which I am assuming is caused by the Public Folders database not being mounted:

Also, the CN=InformationSore is empty. Is this normal?
Now I am assuming I deleted something that I shouldn't have.

Answer 1

Tried that, I get the following when I go to the Public Folder Management Console:
Cannot complete the operation because there isn't an available public folder database on server
And even if I did that how does that help me retrieve my missing information?
