I connected my J3 to a mac to recharge it and lost ALL SONGS on the internal memory.

I'm flying off back to Europe for about 12 hours (two flights) on Sunday and I was happy to have my 40GB of music, though the battery even when fully charged may not last long enough.

And since the only PCs in the house are Macs, I recharged the player by connecting it to a MacBook.

And I now seem to have lost everything that was on the internal memory.

Am I doomed..?
