Internet should have also told you that if you have a real Gibson, chances of actually taking any bit off of the saddle with a nail file is small to say the least. I would even argue that chances are you get into trouble with the missus or whomever you borrowed the nail file from since it will go blunt quickly.
Let's start by taking a magnifying glass and large amount of light to the saddle. If you don't see a burr, there is none. If you see, remove with a real file, round, finest teeth and smallest diameter you have. Worst case is you do not have such a file; take a small bit of 800 grit sandpaper and fold it over a toothpick. If there is no burr, take a good look at the string break angle over the saddle. If you run your strings underneath the stop tailpiece and/or screw it way down low, you alwys run the risk of string breakage. If this is not the issue, then we need to be looking further; in that case post pics.
