It means that your gas was still not enough, or Maybe the token that you attempt to transfer were frozen, so you cannot transfer them, just like me when i attempt to do that.
So, what crypto exchange did you use? I suppose that would be Etherdelta, right?
I'm holding my coins until today because I couldn't make any transaction because of that issues that never give me a clear instructions on how to get from here to there.
Myetherwallet is my first wallet and I'm so happy with it because I can see all my coin collection within a single wallet but when it comes into conversion from one coin to another is like my nightmare.
