Hi, Rachel. Welcome to Just Answer.
No, running another cycle will not help. The razor blade is your best hope I'm sorry to say.
If the razor blade does not get the film off there is another method that will work, albeit a bit drastic. Go to an auto body shop and ask if they have a sheet of 2000 grit wet and dry sanding paper. This is a very fine grit sanding paper and will not harm the glass. It is so fine that you can polish out scratches in glasses with it.
Keep the surface wet at all times. The wetter the better, and easier, it is to remove the film.
This will take some time and a little elbow grease to accomplish , but the results are worth it.

Thanks. So . . . . someone at work suggested 4oooo steel wool. Which is easier to get and would work best for the scratching. The same co-worker who suggested the steel wool felt the razor blade might scratch the glass.
About keeping it wet . . . well of course these things always happen at the ideal time and we're going out of town for the weekend. Should I do something to try to keep it wet while we're gone -- or just make sure it is wet when I return to actually do the work.
