I'm getting this message on almost every file I open with Photoshop CS6 (I had CS5.5 and this never happened).
Besides not being sure if any one of the options could screw up my file, which worries me a little bit, what is really lacking here is a "don't ask again" checkbox. It's becoming maddening, especially considering I do batch processing and it asks this for every file. what can I do?

Missing Profile
The RGB document "X" has a file format that does not support embedded color profiles. What would you like to do?
- Leave as is (don't color manage)
- Assign working RGB: _
- Assign Profile: _
- [ ] and then convert document to working RGB
