@r!sc unSafeDisc won't work on Aquanox

[Peacemaker2000]

i copied the game, and everything went fine, and i thought it's enough that i copy it, and then unSafeDisc it, but everytime i try to dump the "aquanox.exe" it produces a fatal error and then a message-box pops up with this message: "GetThreadContext failed. process allready finished??" but the no "aquanox.exe.data.bin" was created!!! so i can't rebuild it, where's MY fault???
