I have a high speed BADASS computer and every single time I use Adobe After Effects it CRASHES. It is really pissing me off. I need this program for important projects! This needs to be fixed RIGHT AWAY!
The first step is learning how to ask for help. Try again.
Update Creative Cloud and your drivers. Make sure you don't have corrupted fonts. Make sure you are using compatible footage. If you are new to AE then you may likely be having problems related to program conflicts, incompatibility or a thousand other things. Without specific details it's impossible to tell what is going on.
