This is almost always indicative of an upper tension problem.
First, make sure you're using a good quality thread. If you're using thread that's not of European manufacture, you're probably filling your tension assemblies with little fuzzies. Coats and Clark Dual Duty is the most notorious thread for causing tension issues. If you have a bunch of this thread: throw it away or use it for hand sewing.
Turn your machine off, and use some canned air to blow out your upper tension assembly. (It looks like a couple of little cymbals inside the thread path.) Set your tension dial to 4.5.
When threading, right before you actually thread the needle itself, and with the presser foot up, "floss" the thread back and forth by holding the thread at the top by the spool with your right hand, and down by the needle with your left hand. This will ensure that you force the thread into the tension assembly.
Also ensure that your bobbin is oriented the right direction, but this would be a less common cause for your symptom.
If none of these fixes work, you probably need to have your tensions professionally calibrated.

It is held in with 2 small screws but to remove it you must take out the feed dogs first.This is not really necessary. Get something sharp( like a small seam ripper that you may never use again) and cut the thread.Pull out what you can and then try sewing again. Should work.

No but I will be taking it to a Janome authorized repair shop and pay them thanks anyway. G

If its that hard to turn its needing service. Oiling and lubrication are so important to a smooth running unit. If its that hard to turn the only solution may be to get it into a store for repairs.

I had this same problem, on my Designer Diamond. I blew it out with an air can and that didn't work, but then I decided to turn it off, then back on and start sewing a line in reverse. That seemed to fix it. My machine is working fine now.
