It was me! I sat there vigorously watching your download for 8 hours just waiting.. waiting.. 97%....98%.... 99% .. then HA! I cancelled the download! HAHAHA "I bet he's mad now!" I said aloud, whilst thinking "You really are an evil genius, Ed."

Seriously.. there's more to life. Get over it. Chances are on such a large file it's going to be on 99% for a while. Anything could have happened in that time like CyberStalker said, connection trouble, turning the PC off, anything, not even knowing you were downloading that file.
