Yeah it took me awhile to figure it out too. I kept referring back to page 1, checking the patch, the szs file I was patching etc. Kept getting an error. Once I noticed the file sizes were different, I thought..... well . LOL
EDIT.... Anyone else having trouble with moonview highway (space road) freezing upon startup? I thought I patched it right but may not have.
Repatched it making sure to patch the ridgehighway_d.szs then replace both,works like a champ now.
