Check https://www.berninamanuals.com. They might have one you can download.

I know there is a retired Janome Memory Craft 5700. That manual is available on this site: https://www.janome.com/support/retired-machine-manuals/. The current link to this manual is https://www.janome.com/siteassets/support/manuals/retired/embroidery/inst-book-mc5700.pdf .

Please check if this manual is the correct one for your sewing machine. I am unaware of any other sewing machine brand with a Memory Craft model line in my area (USA).

(I thought initially the Nina 5700 might refer to Bernina 570QE; that manual is on the product support page: https://www.bernina.com/en-US/Machines-US/Series-Overview/BERNINA-5-Series/BERNINA-570-QE#!support . The direct link to this manual is https://www.bernina.com/BERNINA/media/Support/Sewing_Quilting_Embroidery/5_Serie/BERNINA_570/Documents/EN/0365315-0-04_2015-05_Manual_B570QE-B555_EN_online.pdf . )

Rethread the machine both upper thread and bobbin thread. Make sure you do not have a bent needle. Clean out any dirt and lint around the bobbin. See is all this helps.
However is it a Nina or a Bernina?
