Typical bullpoo

My sewing machine HAD to have a nervous breakdown today...it just had to. I'm so bitterly peed off! The string kept getting jammed under the bobbin holder and I noticed it was popping up so I took it out, cut out he mess of string and put it back in....but it won't lie flat in it's place anymore :/ tried to sew again, same shit. It's broken.

Now I have to wave one of my projects bye bye until I can get it fixed which puts delay on me setting up shop ( tfou tfou al ain!), and if it can't be fixed (which I really hope not, i'm sure this is a common problem amongst sewing machines..no?) at least I have a guarantee on it. Just not sure if it's still valid...today is has officially been pure shite.
