Maya freeze

[pekinessa27]

Hi; on friday i made a simulation to test the program; got to the point of doing cache and starting rendering process (only 7 agents it was just a camera test) but due to time i had to cut the render short. Today i arrive to continue doing render and light tests and whenever i try to do something to either the lights or the agets maya freezes (it does not send fatal error just stops responding) 
what happened? is this because of Miarmy or because of my computer?
