The +123 Mod has been updated to v2.2 and is available here
. There are a couple maps that will conflict with the Conversion pack if you have it installed as Bokken mentioned. The +123 Mod won't change any of your originally installed SWBF2 Game files and the download is only 154 MB. Remarkably small considering it's adding in excess of 123 maps/modes to your SWBF2 game.
