Question

Just purchased CS6 Illustrator - after 30 days trial -
but then just keeps crashing, everytime after few minutes launched
+ I read fontbook issue but Fontbook says there is no dupe fonts
+ I read about deleting Preferences but which Preference files? (no exact names are mentioned)
+ Or folders?

Answer 1

which,
You may see the instructions about preferences (folder) in 3) and 4) in the list below; and it may be worth looking through 5), too.
You may try the following (you may have tried/done some of them already) and see whether it helps (the following is a general list of things you may try when the issue is not in a specific file; 3) and 4) are specifically aimed at possibly corrupt preferences):
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool if you have CS3/CS4/CS5/CS6/CC, and reinstall.
