[NA-User] Error code??

[BlairBates at aol.com]

A (new-contester) friend asked me to review his log from a recent contest and 
e-mailed to me his .QDF file.  When I attempt to open it in NA I receive the 
following error message.  

<<Error 05 occurred in module NA_Start at address 4CCD:200C>>

Anybody know what this means?  We're both running NA10.59?  

Also tried to open the .QDF file in NA10.56 and got a similar message <<Error 
05 occurred in module NA_Start at address 3B14:200C>> 

Thanks & 73,
