Blindside wakeboard screw holes

I recently tried moving my bindings to a different setting on my blindside board. There were about 3 or 4 holes that my screws would not screw dowwn in to. They may be stripped or somehow got damaged. Is there any way to fix those particular screw holes???

Sometimes the holes get dameaged and sometimes they are filled with fiberglass that does not get completely removed from the holes. Determine what the case is. If it's the fiberglass is still in there you can get a little tap from the co. to strip any unwanted material from the holes.
