Please help, uploaded a F1 mapping that has overwritten every other mapping

I uploaded a different mapping for the F1 than the default, and it had overwritten every single other mapping from Traktor, including defaults, completely gone from my computer. Now, my X1 and F1 wont work because I had deleted that downloaded mapping. Could somebody please provide me with a solution or send me the default mapping folder for controllers? I would be so grateful. Thanks!!
