Importing of MP3 files into DJ Mixer and our other mixing Apps doesn’t work in the newly release iOS 5.1 due to an iOS 5.1 bug. We have implemented a work-around fix that is going to be offered as a free update.
The new update is pending approval by Apple that will address this issue so please stay patient and keep your eyes out for the update. We are doing the best we can as fast as we can.
Thank you for your support and feedback
