9.1.8 update install problem

Having a problem installing the 9.1.8 update. I have tried multiple times and it hangs up near then end while "moving items into place" or something like that. I let it run over night on one try and it was still stuck. The update installed fine on my iMac. I'm just having problems on my black 13" late 2006 macbook running Lion 10.7.5 If I get info on Logic Pro in the apps folder it says version 9.1.8 but software update still wants me to update.

Thanks!
