If you don't have the .pwn file, you can't upgrade your server to 0.3d, 0.3e or 0.3x. You would need to compile your gamemode with the newest version, which you can't do without .pwn.

If you bought your gamemode, I suggest you to contact the one who sold it to you to make an upgrade.

If you stole the gamemode, then you live with it.
