Illustrator is acting up again...
So, Illustrator is acting up like an idiot again, for reasons that only Zeus knows.
When trying to create a new file, instead of the usual dialog box with all the options and settings, this is what I get:

A blank box, with nothing else to to but close.
I've done the usual. Quit and ReOpen, reboot the machine... Nothing.
I'm running a brand new iMac, the app is fully up to date.
I just want to know if this is a known issue with any simple solution before uninstalling and installing again (which seems to be the only solution to Adobe apps these days).
Anyone?
