I saw a similar post about this from last year, but with no true conclusion. I closed a document in AI CS5. Now when I try to reopen it, I get an error message about there not being enough room in the window, increase document area. How do I do that since I can't get the file opened? Am I doomed to having a file that can no longer be opened?
This happens with all the file or with new files only..
Also try resetting the preferences :-
hold Cmd-Opt-Ctrl-Shift when restarting AI on a Mac or Alt-Crtl-Shift on a PC to reset the preferences to the factory defaults
Also let us know your OS
I know thiis is late, but I am also having this issue. I haven't been able to resolve it, but what works in the meantime is, when it gives me that message I say OK, then maximize the Ai window then go File, Open Recent, and what you attempted to open should be there...and it will then open.
I don't know how to get the message to stop popping up though.
