Channel Setting Window Issue **URGENT**

Hi Folks

i just encountered a really annoying problem while mixing. for some reason i was play in with my channel window, ( e ) on the mixer channel, and went in customize view. after playing a little around i ended up only having the fader as view. then when i unchecked “fader” in the customize view i ended up with a little box (very small) with just the “x” sign to close the window. does any one as any idea how i can get things back in order…please i really need help as i have an upcoming project coming this week end and i’m so used to using that feature in fact i stopped working because im so frustrated from looking at all the options possible. someone please help!!!
