[LOGic] large scale replacement of text

[Ray Boehmer]

I need help with a procedure for replacing some erroneous info that got mysteriously inserted into LOGic by a contesting program that I used last weekend in the ARRL DX TEST.  I need to replace the incorrect callsign that was put in the "Operator" field with my correct callsign.  This would be necessary for close to 300 qsos, so I am hoping there is a quick and easy way to do it.
 
LoTW will not take my data until I make the changes.
 
Thanks for any help you can give me.
