first off, did you relocate the file? meaning were ever you had the chopped sample save at at first, did you moved it? That would be the first thing i would check
If that dont work
Then go to your main hard drive and locate and click on program files-> click image line -> then click the version of fl your using -> click data->click patches- Then the last thing you would have to click is sliced beats. See if you can locate it there. if not then most likely its gone or in the recycle bin. Good luck
