Unsafedisc 1.5.5 and Windos XP

[Cowsheep]

Is it normal that Unsafedisc 1.5.5 can only unpack SD up to 1.41 on Win Xp?

1.45 and 1.50 fail with excepetion occured in do_safedisc_shit @ 0001e078h.
(Both game exe and usd are in dep exception list.)
Tea key got till 1.41 4 equal blocks, 1.45 and above got 4 different blocks.
Maybe thats the reason for failure?

Any working unwrapper for 1.45 and 1.50 out?
