I just installed CS3 a few days ago. I was fine with CS2, but I needed the upgrade in order to open some files from another system that were saved as *.ai CS3 files. Yesterday, I was working on a project and to my shock, horror and dismay, I couldn't save the file. "Could not save the file because of an unknown error [CANF]" is the dialog that appeared onscreen. I figured, "Okay, I'll just select all/copy/quit/relaunch/create a new document/paste, no problem." Wrong. I also could not copy anything to the clipboard.
I Googled the "CANF" error. Seems to be a complaint among many CS3 users. The fix I found (for Mac 10.4.11) involved moving the AI Preferences folder contents to the desktop and relaunching AI. I did this. No more "CANF" error, but now when I try to save a document, "An unknown error occurred." pops up.
Has anyone else had this problem with CS3? If so, what fix will work to correct these error messages?
I have tried that method. It always worked for me in previous versions of AI, but not this time. I've gone through all of my old tricks, changing the filename, changing the save to location, trying to save as *.eps, trying to save as a Legacy *.ai file. None of these work. Thanks for that tip though.
Additionally, it seems that Windows users have this issue based on a conflict with Zune. I don't even know what Zune is, but I'm not running it, and I'm on a Mac. Dumping the preference files didn't change anything for me.
I have to admit that I wasn't even aware that there was a CS4. We're running CS3 at work, so I figured that was the latest version, because they're usually pretty good about upgrading as soon as there's a new product available.
If I had known that this thing was an issue, I would've stuck with CS2.
