sims 3 crashing when in live mode. help please!?!?

i have been running sims 3 on my netbook with all expansions for a few months now, no problems only a little slow. now i cant even play it. i can build and buy but as soon as i go to live mode it crashes and says sims 3 has stopped working and windows is checking for solutions. im not sure why this is happening. i know that my system requirements are low (intel atom n455 2gb) but i have everything set to low and it was working fine. can someone please help me? will be much appreciated!!!

Do you have any Mods or CC, You probably have either an outdated mod, or a mod that is clashing with another mod in your Mods folder.

Hi there,

I was hoping you made a typo when you said "netbook".
