Hi  
I have created a weighting file to compensate the frequency response of my QA402 (actually I did a file for each sampling frequency). When I add a line “LOGINTERP” in the header of the file, I get an error message “Weighting file exception” and my file gets deactivated. Whithout this line, the weighting file works as expected.  
I have also tried “LOGINTERP” in an RIAA weighting file where it works without problem.  
I’m using SW version 1.194.  
Any idea what the problem could be?
