When I have that issue, it is usually my needle that needs changed. I see you stated that you changed your needle, so perhaps the tension is too tight.
I'd give the needle change one more try, and put in another new needle. Sometimes it is also possible that the needle is not put in correctly and the eye is not facing the way it is supposed to.
I use Connecting Threads Essential thread. The machine I use is a Baby Lock Accomplish - High Speed straight stitch.
