Some users have experienced difficulty with SAACR_raw2raw_concat crashing as soon as the application is started. This problem can arise if the following configuration files become corrupted or are left with an invalid configuration


C:\Measurand Inc\SAA3D\pref_rc.mat

C:\Measurand Inc\SAA3D\last_fname_rc.mat


Deleting both files will allow them to be reformed with default values, and SAACR_raw2raw_concat should be able to startup normally.
