Glucose meter stops working first day of holiday... help

So I'm living in the UK, on a one week holiday in New York, and today on my first day my glucose meter (Freestyle Insulinx) decides to screw me and give me an error message (error 4) that I have never seen before (it was working fine this morning though, but since I can't get it to work). It will do that every time I insert a test strip or turn in on. I have no idea how to fix this, and costumer services are closed atm.

  1. Has anyone ever had this error message before, knows what it is or knows how to fix it?

  2. If I can't fix it do you think it's possible to go a week without measuring or will Bad Things happen?

I'm type 1 btw. Any help is much appreciated!!
