Hi sudek, try not-humidifiying the paper and putting 1 or 2 mil (25-50um) thin clear polyester between the coated paper and negative first. This became my standard practice after ruining a couple of negatives. The step tablet comes later when you figure out what happens right now.
Edit: BTW, I reading again I see I've made a mistake, you don't cover the steps as I described above, you open them, I wrote the other way around above. You expose the first step 1 minute then open each step on each stated time. You must use a chronometer not timer (which counts backwards). Sorry for the inconvenience, it's long time I didn't it that way; step tablets makes people lazy! BTW, one plus of step tablets is that you have the same base for comparison with other tests and tests of other people...
