Hi folks, so here is my trick: Before converting .wma into mp3 files, just disconnect your internet connection!! Then go on by selecting the files or folder to be concerted, the silly window appears again claiming you need "components", then Switch tries to connect to the internet, of course impossible now, an empty sheet in Safari appears, just go back to Switch & confirm that new components were installed, & then you can convert one file after the other. The unnecessary internet-connection which otherwise always appears after two converted files won't bother you no more. I hope I didn't forget anything. Try it, good luck!
