MP3 Conversion in n-track v9

Hello, my first post here. I didn’t see this answered elsewhere in the forum. I just upgraded to v9. While I’m able to convert/save files to mp3, they aren’t playable on all devices (e.g. iPhone and other Apple devices). I had the same problem in v8, and always had to do through iTunes. I removed the Lame dll and downloaded latest 64-bit version. n-Track didn’t ask me for file location when I went to convert to mp3, so not sure what’s going on. Any suggestions will be appreciated!
