Mutt: Maildir & "Mail/IN*: No such file or directory"

[Adam Bogacki <afb@paradise.net.nz>]

Re. Mutt giving me blank screen with the message
"/home/adam/Maildir is not a mailbox"

and the terminal telling me that
"find: ~Mail/IN*: No such file or directory"    

is there a conflict between the 'Maildir' paragraph  
and the following 'Mail/IN*' below [.muttrc] ?
