agi studio on windows xp

cosmic r I recently installed windows xp on my comp and now agi studio is now saving logics. it compiles fine, but when it goes to save it says cannot create directory "D:\game\\src". is this an xp problem or something else? please help, as I'm so close to releasing a demo.
