On the program magix movie edit pro 15, under the edit tab on the top right i accidently pressed the x on all of the little boxes and got rid of everything and now when i click on the edit tab all i see is gray, how do i get them all back?

-the problem is i can't get all of the boxes to come back, for example: the timeline, or the little box that lets you watch it all together

-how it occured is was i accidently pressed the x button on all of the separate boxes 

- i am using magix edit pro 15 

- i am using windows 7 operating system
