Maple wont start (Error -214767259)

After installing Big Bang I get this error when trying to launch from web as well as from the game launcher in the Maplestory folder. I tried uninstalling and re-downloading the game (and checking for graphics card driver updates, downloading directx like nexon suggests).
It starts up hackshield, then the error pops up before maple even opens. It worked before the patch. I have windows Vista if that helps.
I tried searching for some answers but didn't find much help, anyone know how to fix this? thanks!
