your playing Gold Version of the mod. The mod is mainly designed for normal se4 not gold, although a gold Version has been made. The latest non-gold Version is .30 where the latest gold Version i could find was .29 which is one update behind the non-gold Version which sorted out a few but not all of the bugs.
The non-gold Version can be foundm on the PBW website as said below. the only gold Version i have found is in the general mods forum in the se4 thred on mods etc. ( i gave better directions to it a few pages back in this thred.
