clip zip stopped working transferred music to cllp sport 1/2 songs not playing

As the title said I had a stuck back button on my clip zip so i bought a clip sport on best buy transferred the music from the clip zip to clip sport and many songs are not playing.  Is there any fix to this issue?

How many files are there on the new Sport? It has a database limitation of 2000 (int. memory) & 2000 (sd card). If you have any more than this, the excess will be ignored (aka not seen).

The new firmware allows up to 4,000 songs for each database.

that is a beta FW. I have not seen any post where it will become the new standard. the official release is still limited to 2000 internal and 2000 external.
