Hacking Wii Scrubber

[kehabouter]

Hey guys,

i have a question,
when i use the wii scrubber 1.4 with multiboot and i trim an iso everything goes fine.
but if i try to re-open the trimmed iso i get the error io_seek.
how can i fix this ?
i am currently running on w7 ultimate, is that the problem?

i tryd just to hold enter, but that takes 20minutes and then the io_seek is still there.
can anyone help me?

greetings
