I just recently bought a MF lens and an adapter. I have the menu setting adjusted properly and still cant get the camera to work. Yet it will work with a different adapter. So does the issue lie with the camera or adapter?

Make sure you're in "A" aperture priority, whereby you adjust the lens aperture manually and the camera sets the appropriate shutter speed to achieve correct exposure.
Some adapted lenses won't permit you to adjust the aperture directly on the lens. Do this: with the lens removed from the camera, hold it up to the light, turn the aperture ring on the lens, and you should see the aperture change size. If you can't do this manually, then you can't use the lens on a u4/3 camera.
This also means that almost all non-u4/3 autofocus lenses won't work either, since they require the camera body to control aperture and focus electronically, rather than mechanically.
Also, when adapting manual lenses you will have to focus the lens manually, using the focus ring on the lens itself. The focus may be so far out that you're not seeing a clearly defined image. Try using the distance scale on the lens, set it to about the distance of an object you're pointing at, and then see if you get a clear image.
The angle of view, when using adapted lenses, will be equivalent to a lens of twice the focal length if used on a 35mm film camera. So that a 50mm lens looks like a 100mm telephoto, etc. Perhaps you're trying to point it to something too close?
