L2J Server

I have a question. to new l2j version i need new system folder? For c5? plz help my if i need plz some download link

C5 is by no means new. If you need a C5 installation, grab these files:

http://l2jdp.com/svn/C5_Datapack/C5_Datapack.tar.bz2 (latest C5 datapack release before switching to Interlude)

http://l2jserver.com/nightly/L2J_Server-c5.zip (latest C5 core)

Mixing datapack/core builds from another revisions, either older or newer, will most probably than not produce all kind of errors and malfunctions that, as you can probably imagine, we cannot provide support for.

Even further, these C5 archives are primarily kept for reference purposes. If you find some bug or lacking feature you'll gonna backport/fix on your own.

Good luck.
