Missing files in .Minecraft

A few days ago i decided to play minecraft, It started up like usual until it got to about 90% of finalizing procedure. about 3 seconds later it said it has crashed, so i looked at the crash report saying Minidump error. i was used to this as it happend a few times before, all i needed to do was go into appdata, click on .Minecraft, go into options and turn fboenable;true to falso, but when i went into the .Minecraft file the entire options file was missing. Please give advice.
