Thanks Todd, I hadn't realised a new update had been released which seems to have helped - along with turning off Render multiple frames
EDIT - Spoke too soon, looks like I'm still having the same problem

I still need help, anybody...please!
You could try this for a check...
Go to your system preferences and create a new admin account.
Then log in to that and open your project.
That will force AE, its preferences and all caches etc to be re-created.
If your problem still persists after that you might want to make sure that one of your RAMS (Memory Blocks)
I cant remember how to test such as I believe the apple hardware tests have gone by now.
Also, when trouble shooting such - try to disconnect any peripherals from the mac, if possible...
You might also want to make sure that your media caches etc are residing on a FAST drive
instead of the default ˜/Home/Application Support/Adobe/Common
Also try the following if none above works
1) save your project prior to rendering
2) Choose the EDIT menu - PURGE ALL
3) Go to preferences and look at the Media and Disk Cache section.
You WANNA put those on a FAST drive. Also you could try to delete the caches from within there and disabling the disk cache
PRIOR to rendering...
