Either you hid the Preview window, and are looking at the greyed out Play menu option under the Preview menu at the top of the screen. In this case, just show the Preview window again (View / Preview from the menu).
Or, you have the Preview window there, and clicking Play just seems to do nothing, but you can still drag the slider left and right. Also, in this case, File/Render doesn't do anything either. This means that you did not purchase the software from us, and are using a pirated version that was hacked to remove the trial screens. Your trial has expired, and Play + Render are no longer available unless you purchase the program. The screen that would tell you this has been removed so the buttons appear to just do nothing when clicked.
