Do you mean when you try to extract the zip file it stops during the extraction process and gives the error? Once you download the zip folder and extract that, or do you mean when you are loading the 3rd disc into the emulator it is giving you an error?
Viewing post in [Fixed:Non-Issue] Issue Extracting ISO 3
When trying to extract the blackout-linux.zip file, (English/UK Version) not loading the emulator. I used WinRar and it gave a checksum fail specifically for Disc 3 then I used Windows built-in unzipper and it produced a generic error. ('0x80004005')
I tried again today using 7-zip instead and it worked. I also tried it with WinRar again just to test things and.. It worked.? Don't know why it suddenly worked this time. Probably a me issue because it doesn't look like you updated/changed anything.
Sorry for bothering you with this. I'll edit the topic title so it doesn't turn people off from downloading.
