I have the same problem with my acoustic which I understand is common. Around the 14th fret? On mine it causes a problem just with the high E string. I was told there are a coupla ways to fix it involving messing with the frets in the area, up to a neck re-set. Easiest might be an adjustment of the fret, I am told, even by tapping it down a little. I am going to have mine addressed sometime soon and I will let you know what ends up being done. No expert here, just passing along what I have been told.
