[Dxbase] N8S Mapping Problem

[crownhaven]

When I logged N8S, it defaulted to "K."  I wasn't thinking and manually 
changed it to KH8.  I got the question, "do you want to map N8S to the 
KH8, etc." and said yes.  I continued to log the rest of my QSOs to 
KH8.  I just figured out that I made this mistake and tried to change 
the prefix in my log to KH8S.

First I get the "do you want to map N8S to....." and I click yes.  Then 
I get an X that says, "the changes you requested to the table were not 
successful because they would breate duplicate values in the index, 
primary key, or relationship.  Change the data in the field or fields 
that contain duplicate data, remove the index, or redefine the index to 
permit duplicate entries and try again."

Of course, if I click "no" to the first question, it doesn't change the 
prefix.

Next, I went into "tools," and then "database access."  I found the call 
N8S in the prefix database under the "call map."  I changed the prefix 
for N8S to KH8S.  I initialized the tables, rebooted.  No changes.

If I log N8S now, it still defaults to KH8 and I cannot change the 
prefix in the previous QSOs I have logged from KH8 to KH8S.

Help!!!!!
