MP3's won't play on Traktor Pro 2 HELP

I have a library of about 3700 songs and 700 of them won't play. It's say's .mp3 could NOT be played due to a missing or corrupt file, unsupported format or DRM-protection.

I'm using the latest Traktor 2.1.1

All of these songs are legal and downloaded from beatport.

any advice or info would be appreciated.

Have you tried reloading them into your track collection again?

Check the consistency of your traktor library, then see how many are missing. You can also click relocate select your music folder and go away for awhile while Traktor finds the files.
