Lost path First Storage Group Exchange 2007

I seem to have lost the path information in Exchange manager Console in regards to the First Storage Group & Second StorageGroup. I relised I had this problem when I tried to create a new user and receiving a cant find database error.
Fortunatelly somehow the emails are still working therefore the database is still mounted.
I also noticed using Exchange management shell I was receiving the same error when using get-mailboxstatistics
Does any one know how to re-instate the paths for Exchange mailboxes, I have serched the Internet, but it dose not look if anyone has had the same problem.

Thanks in Advance
