breakpoints not working [RESOLVED]

Hi
I get the most strangest problem with breakpoints. It was working fine, and now its decided to stop working.

I have a fucntion that I want to step through the code with, so I add a breakpoint on the function line like i always do, so I get a red dot and a red line indicating its a breakpoint.

When i click run, vs.net doesn't go into the breakpoint mode when that function is called. If i look at the IDE while my program is running, the breakpoint now has a question mark inside the spot.
If i hover my mouse over it, the tooltip says

"The breakpoint will currently not be hit. No symbols have been loaded for this document"

it happens on all the breakpoints that i add

What gives?

Doh!
I had my build on release and not debug
