I purchased the 12 month licence for Apowersoft video converter studio but only seem to have the trial version. I tried to convert 2 M4b files to mp3 but the result was 2 mp3 files that are only about 40kb and don’t play. I’m not sure what to do to correct this. Any ideas out there?
Sorry, please send us your order information, and then we will help you activate your VIP account. If you don’t mind, we would recommend you to send the 2 m4b files to us via email@example.com. We will help you test them soon!
