I haven't seen any fixes yet either, but changing the date to 26 Jan worked. I tried changing it back to 27 Jan and opening PHUD, but received the same errors again. It''s a temp fix, but at least it works.
We are currently updating registration codes as needed, and we do expect that the process will finish by the end of the day today. You can feel free to just try booting up PAHUD and if we have gotten to your code, it will work as normal.
