Power Profiler Kit fails to measure milliamps correctly

Today when I started power profiler kit, it suddenly started to show peak values like 80 mA. This has not happened before, but the values with the same hardware have been around 20-30 mA. So I checked what the PPK shows with a fixed load, using 3.0 V and a 330 ohm resisor. The result was 64 mA, although it should be 9.1 mA (= 3.0V / 330ohm).

Then I tried to reflash the PPK with flash_ppk.py with no help. What could be causing the thing, is there any way to fix the problem? Below is the pivture what I see with the 330 ohm resistor.
