Downgrade help

NEED A DOWNGRADE!!!!!!!

At the moment i have just upgraded to OS X 10.7.5 . But some of the sofware programs i use arent updated yet and dont work properly for some reason unknown to me. I just need to be able to access them until they are compatible 10.7.5 , I need to be able to run these programs for work so if someone could help me downgrade to 10.7.4 just until the software is compatable with 10.7.5 that would be great thanks 🙂
