If that's how all your new projects start, try reloading the new project template of your choosing. If it still doesn't fix the problem, turn all of them on and save over the old template file (located in C:\Program Files\Image-Line \FL Studio 10\Data\Templates\[nameoftemplate]). The template files are in folders that have identical names to the templates. The template you start with by default after installing FL is "Basic With Limiter", I believe.
