APTX Prop Packs Problem

[jpj_starfleet]

I am having a problem with some of APTX's lots after installing the MEGA prop packs, the Nippon Shipbuilding craines and ships are missing and so is the Cerulean Hotel and East Jpn Co HQ bldg, I installed the prop packs and ran Cleanitol so it removed the Desc & Models listed on the doc's but the Prop Packs are not filling in the missing parts...anybody have any idea what might have happened?  Thanks
