We've been experiencing an issue with saving illustrator files (as .ai). The error message is "unknown error occurred" when attempting to save. Things tried already:
delete preferences file
uninstall/re-install CS6
standardize all fonts to arial
save in another location (desktop, network)
save as .eps
But still same.
This happens when copying components of one ai file to another and trying to save it. Found that removing one tiny piece from a drawing allows the save...so fine we can work around, but it would be really helpful to know WHY this is happening, because it seems likely to happen again. There is no text in that piece, just lines and shading.
Any advice is appreciated.
