Any chance you fiddled with your screen resolution? Probably the number one reason for losing items on the screen.

Are the rest of the buttons there?

I recently upgraded from Artist ver 2 to Pro ver 2 and I am dealing with this same issue...My Fast Forward, reverse, and jump to mark buttons are missing from the transport. when I open the project page they are there. I use these buttons extensively. I have not change my screen resolution...How do I get them back on my recording page??
