PS3HEN error 80010002 when trying to run games with multiman

[Strix_y]

So as the title says i have problems when trying to run iso games off an external ntfs hdd with multiman. Out of 85 games only i have this problem with like 18 or 17. I ve seen a post saying hen 2.2.1 doesnt have this problem but i cant downgrade on HFW. Am i supposed to ignore this problem and maybe wait for a fix or convert the games back to folder format?
