Thanks Joe! I removed the motor and still the same. However, after some close investigating, I figured it out. Somehow the thread cutter had got turned towards the side/front and that is what was stopping the needle bar from making a rotation. Now I have to reinstall the motor, which is good, I watched a video to see how to do that for future reference. Plus, the machine is all clean and greased and I will take her for a test run shortly. Again, thank you for your quick response.
