I would say stop drilling.
I'm having trouble picturing where exactly it is that you are trying to place the brakets. I have a feeling you may be drilling into a piece of metal though.
Depending on your style of window, you may have a retraction device which aids in lifting and keeping up each sash. If you look in the side jambs above each sash (pull the top one down) you might see a cord there which disappears into the top of the window. There's often a box inside the top of the windows which retracts those cords (much like a tape measure). Drilling through that box could destroy the mechanism.
A solution may be to raise the bracket higher on the moulding so as to avoid the box. The higher the better, but you can usually get away with 2" up.
You may have a different kind of window also, but these are pretty common and I wouldn't want you to do that kind of damage to your window.
Additionally, if you're drilling close to the jambs and they're metal covered, you may just be drilling through those.
