I received this tip from different users at the forum, and this proved to work:

For those with problems starting the game after the patch, don't use Winzip. Try to uncompress the patch with 7Zip or WinRar.
Winzip apparently works, but the result is that the game crashes right after starting it.

Thanks Bounder! and David198502 for advising. Devs, I think that this is important to be noted on the first post.
Now for the testing!
