ExpatShield not passing data to application

Greetings guys, hope you are doing fine.

I'm using ExpatShield to play SCII ( long story ). Anyway, I tried today to download an arcade map from within SC ( 3 MB ) but it was extremly slow. I alt-tab and opened Resource Monitor and here is what I found >> http://imageshack.us/photo/my-images/33/expatbug.jpg/
As you can see ExpatShield is downloading at near 70 KB/sec but is not passing data to the original application ( SC in this case ). It actually downloaded more than 70 MB and the map was still at 2%. Moreover, when I exited SCII, Expat kept downloading.
It usually works fine except for this case.

Thanks in advance.
