Broken Monitor, and missing LH surge question.

Hi! I was on day 4 of the flashing smiley face... and when I went to test the next morning the monitor gave me an error symbol (or the book). It had not gotten wet or anything! I'm so frustrated b/c I was right in the middle of testing. Is there anything I can do? It was a fairly new kit, and they are so expensive.

Also- if I happened to miss my surge- the next time I tested would it be a flashing smiley or go back to a blank circle? Thanks!
