Load old sdcard to new firmware Aeros

Saved my old songs to PC.
Updated Aeros firmware.
It asked to convert songs internally.
I did.
Only 3 of 26 songs made it others converted to 6x6 and no data.
All songs I use 2x2.
So I downloaded my saved song list on PC and tried again.
It loaded for several minutes mabey 10.
Now I cant locate anything?
About to start re recording all of my material instead of chasing this around.
