| Since you just replaced the strings, it sounds like the slot in the nut is too narrow for the new E string.
Look at the string and the nut very carefully, with a magnifying glass if necessary. The string should be sitting in the bottom of the slot. If it's not, you need to widen the slot WITHOUT MAKING IT ANY DEEPER!
A small round or flat file will do that--only file on the sides of the slot, don't touch the bottom AT ALL. You could buy an expensive fret file from StewMac, or for just widening a slot you could use the smallest "jeweler's" files you can find at a hardware store.
Just don't touch the bottom of the slot. If you have them, put a stack of feeler gages on the fretboard, to prevent the file from reaching the bottom of the slot.
You probably only need to take off a few thousandths of an inch (the thickness of a piece of paper), so go slow and check the width with the string often.
Just be careful. Don't scratch the headstock with the tip of the file.
