[Dx4win] Adif Import

[Mm0eax at aol.com]

Trying to import an adif report from the arrl Lotw, the first time i did  
this everything checked out fine and Dx4win tracks my Lotw stuff excellent, now  
i am trying to update my latest confirmations following the same  instructions 
as i did the first time, i have my adif reports from the arrl which  i have 
opened and confirm they are all there 100% but my problem is Dx4win won't  read 
them when i try to import? Using Imported QSO sets Upload Confirmed  Flag ! 
Is there anything i may have overlooked?
    Strange as it worked fine originally anyone have any  suggestions?
