My polaroid film won't develop

I have a problem with my polaroid film lately. I think it won't develop but I really don't know the problem. The pack was from November 2015 and it is an impossible color 600. The photo's where from December that turns out dark blue. I have a sun 650 Polaroid. The photo's are dark blue (like when they supposed to develop) then I saw some white stripes (seems like fingerprints) on the photo. And no, I haven't touched the photo while developing. I'm looking for the answer why my photo turned out like this. Is it the fault of me, the camera of the film? What did I wrong? Please help!
