Is the left side of the image longer than the right side or vice versa? Basically, this is a horizontal keystone condition and is caused by the front of the projector not being parallel with the screen. If both sides have the same length, the projector is not level --- right to left.
If the top and bottom of the image are not the same length, then the projector is not level front to rear.
I know nothing about the mount that you got but sometimes the less expensive mounts have an irritating tendency not to hold the adjusted position when the clamping screws are tightened. (I actually built my mount using the ideas of an AVS poster. It uses two plates. One plate is connected to the mount and the second plate is attached to the projector. the plates are connected together with four screws, springs and toggle nuts. This allows for very precise adjustment to level the projector. After all of the adjustments are complete, you put a bit of nail polish on the toggle nuts to lock them in place.)
