Hi 
I have recently upgraded Traktor 4 from 4.0.2  to 4.1 
And didn't realize immediately that all my stems (that took me days of converting one by one) are not anymore reconized … 
Actually the stems folder it still there, but the stems icons disappeared from all files I have already converted
I just can't believe the upgrade deleted many days of work and that NI didn't have a solution for this … 
Is anyone know a solution to relocate everything ? 
Thanks you in advance
