R Tate,
This is a link to the UBI forums which has the patch order listed.
UBI Forums
Pacific Fighters was intended to be used as a standalone game or a game merged with the earlier Forgotten Battles + Aces Expansion Pack game. To this end, the patches to be used were different.
If you are trying to patch the standalone version, make sure any patch you use does not have an 'm' at the end (i.e, pf v303m.exe) as these are intended only for the merged version.
If you are still not successful, try posting in the Community Help section as there are a lot of knowlegable folk there.
HTH,
Work
