Some large update just downloaded, two smaller patches for Costume Quest and Stacking were also done so I guess it's a game engine update, maybe those two other titles no longer run at 30 frames per second.
Unsure at the moment what was updated with Brutal Legend but it must have been something larger due to the download being nearly 800 MB.
(Stacking was 50 Mb and Costume Quest 4 Mb)
Correct me if i'm wrong but i dont think the size of the update really matters as long as the exe changes the trainer wont work..
GOG recently released Brutal Legend with a version number of 2.0.0.5. I have tested the latest trainer (05/07/2013) on Win8 x64 and it, unfortunately, does not work. Hopefully this trainer will get one more coat of paint.
Edit: And as usual thank you for the wonderful service you provide.
