I've just bought my first month's membership on the creative cloud and I downloaded AE CS6 a few days ago, every time that I've started working on something it would crash during a RAM preview saying that after effects cannot continue and the error (0 :: 42).
I am using an AMD Radeon HD 5770 graphics card, not sure if that's the problem but I've put it just in case.
other specs:
Intel i5 2500K quad core processor
8gb RAM
If someone could help me out and tell me how to stop this from happening, I'd be really grateful!
