Reply to Weird problem with autogain and loading tracks into Traktor

So here's my problem. Ill load a track once and the auto gain doesnt do anything (I already know that in Traktor 2.6 you have to click the little blue button under the autogain and it tells you how many db its adding or subtracting so thats not it). So I load it a second time and then it says the file is missing or corrupt. I try loading a third time and then auto gain works. Any one have an explanation for this or might know how to fix it?
