What does the crash report say?
MacOS 10.9 has quite a few OS bugs that have not yet been fixed, and we've seen some third party plugins crashing more often on 10.9 as well.
I'm having the same problem with my Adobe Photoshop Elements 11. After I edit 5 or 6 photos it will crash just leaving the "has stopped working message". I'm using a windows 7 laptop and this has been a problem ever since I started using the Photoshop Elements 11 software. I came here looking for a patch or update I may be able to download but I'm not having any luck finding anything but the site trying to sell me the elements 12 edition. I'm sure as hell not going to buy something new when the old product is a bummer to use. Maybe someone on the staff can help me out and I may reconsider when I get my new laptop later this month.
Elements issues should be posted in the Elements forums - we can help much here in the Photoshop forums.
Also, this topic is about crashes in MacOS and you are using Windows, so HIGHLY unlikely to be the same problem.
