so some of the cdlcs i download worked before but after downloading more cdlcs some of the songs stopped working still they still appear in the song selection but there album art cover isn't showing and also the music won't play when hovering over it and if u try selecting it it will freeze the game idk if i just have to many cdlcs downloaded or what i followed all the cdlc instructions and downloaded dll file. or whatever it is after having a different cdlc problem yesterday so if anyone can help that would be appreciated cause tried looking in the forums but couldn't find an answer 

Try just installing one CDLC and see if you can play it in the game.  If it doesn't work then reread and follow these directions.  If the one installed CDLC plays then all should work.  You may have downloaded some conflicting CDLC or possibly corrupt CDLC. 

 

Follow my signature link and download CGT (Custom Game Toolkit) then use CDLC Manager feature to check your CDLC.  After you have parsed your CDLC colletion, click on the GUID column header and then select the Custom Duplicates radio button.  This will show you if you have any duplicates (conflicts) that will crash or hang the game.  Also your CDLC will be checked for corruption automatically by CDLC Manager when it parses your song library and if any corrupt CDLC are found they will be moved to quarantine.
