You have to have at least version 2.26 to patch it to 2.3 directly. And it has to be
clean and
unmodified. Some people installed SP modifications (just like me), which is not supported by the devs. The patcher seems to unable to recognize the modified package.
Re-install BF2 v1.5, and re-install FH2 to patch 2.26 (clean) and patch it to 2.3, shouldn't be problematical anymore.
Otherwise, download the full version of 2.3.
Pake torrent kan? Ditinggal tidur aja. Daripada pake incremental gak patch beres2
