I appear to be doing it wrong because numerous times when i extract to the same file it says i need to replace files with the same name because the extracted section of 1 2 and 3 all have the exact same name so they replace each other, further muddying the waters because then it replaces it with half a file because 1 becomes 2 becomes 3, and since 1 2 and 3 wont work unless together neither work because they do not remain as one but get replaced as each consecutive half file.
This would solve itself if the OP had kept version 3 up and downloadable when it was a single file, then kept the patches as downladable patches that could be extracted
