Hey Nick,
I had exactly the same problem. Crashes after 1-2 minutes of random activities.
I ended up going down to 2014.0 and then upgrading to 2014.1. Everything is working perfectly now.
If you are interested to do the same you can go here to get 2014.0: Adobe CC 2014 Direct Download Links: Creative Cloud 2014 Release | ProDesignTools
And then here for the upgrades: All Adobe CC 2014 Updates: The Direct Download Links for Windows | ProDesignTools
Make sure you read the instructions carefully. The 2014.0 link does not work unless you follow the steps.
Here are my specs and error.
