Hi. I'm trialing Switch using the free version. Last night I did a mass convert of my library from WMA lossless to MP3, using the "copy folder structure option" and using encoding options VBR min rate 32 max rate 320 For the output folders I examined (a dozen or so) only 4 tracks were copied for each. Is this a limitation of the trial version, user error, or a problem with the software? Thanks!! Peter
