Welcome to the wold world of Quilting :lol:
As for the machine what kind is it ? Did you give it a good cleaning ? maybe oil, but if you have the manual read it first to make sure you can/should oil it . Sometimes machines can be cranky and you just have to keep trying things until it works. Try rethreading the machine, rewinding the bobbin, new needle.
But most of all have fun :thumbup:
