The Moen Posi-Temp Valve is a pressure balanced valve and when not used for long periods of time they can stick causing only cold or hot water to pass through the valve.
A New Posi-temp cartridges can be purchased at most plumbing supply houses or big box outlets such as Lowes or Home Depot.
As long as you had cold water before, a new cartridge will solve the problem. In the future it would be wise to occassionally operate the valve at least a couple of times a month in order to keep the pressure assembly from becoming lodged in position. Just follow the instructions included with the new cartridge on the proper removal of the old cartridge and the installation of the new cartridge. a little silicone grease inside of the valve before installing the new cartridge will also help.
Be sure that there is no particles of the old cartridge left in the valve.

take out the cartridge from the fixture and make sure it has all of the "O" rings and stoppers.
look at the instruction again, make sue you are installing it the right side up. if all that, the shower still leak, then you need to talk to the place you brought the fixture, it may have a defective cartridge.

try taking the shower head off and see if there is something stuck in it. sometimes things will come through the water lines and lodge themselves in the valves as well. if the shower head isn't clogged try dismantling the valve that turns the shower head on and then turn the water on when its out and flush the port out.

You might have to replace the tub spout, because the divirter is not closing all the way. A new one will stop water from getting by it.
