Gregor, he offered to send me a single pack. I told him my friend bought the same film from him, same exp. date, and he had the same problem. Seller tried to tell me I wasnt pulling the film out right. Whatever. Anyway, I suggested he not try to sell any more of that film. I doubt he'll offer a second pack for my friend, but we'll see.
Also, I discovered that if you take the pack apart leaving the center part together and run your fingers through the negatives, you can separate them and then the pack will work. I tested this out with one remaining pack. All my pix came out solid black, which I dont understand, but the goop spread out evenly and I was able to get 4 pix to come out right. The remaining three had issues. Not sure what to do about that, but anyway, its something. If the film sticks and wont come out, try pulling the pack apart and separating the negatives. It might work.
