Can't save file's in Adobe Illustrator CS ed

Can't save file's in Adobe Illustrator CS ed I've been using this software for awhile now as I have to use it with my graphic design course, but today I tried to save a file and it came up with an error saying:

'An unknown error has occoured'

then

'Can't save preview, but all other information was saved successfully. The file couldn't be found, ID= -43'

Can someone tell me how to fix it? Im on a G4 Ibook running Tiger 10.4.11, it's never given me a problem before :/. Can't seem to find any solutions on google.
