Enable the content recovery mode, then run the recovery on the files to covert them to a format that can be modified in a text editor. A complete explanation is available in How to enable content recovery mode in Illustrator CS2 or later.
When you try to open a file in Illustrator CS4 or earlier, the following error message appears:
"Can't open the illustration. The illustration contains an incomplete or garbled object description. Offending Operator: '%%End Setup.''
The error message then lists the content that includes a tilde followed with a greater-than sign: "~>".
This error indicates that the document contains one or more malformed binary data entries.
Illustrator CS5 implemented a fix for this issue that resolves affected documents when opening them.
Enable the content recovery mode, then run the recovery on the files to covert them to a format that can be modified in a text editor. A complete explanation is available in How to enable content recovery mode in Illustrator CS2 or later.
Open the recovered copy of the file in a plain text editor such as TextEdit (Mac OS) or Word Pad (Windows). Use a more traditional word-processing application and save the file as plain text without allowing a hidden .txt extension to be added.
Search for the following string:
%_/Binary: /ASCII85Decode
This string is followed with text that includes a tilde followed with a greater-than sign:
~>
The subsequent line is in the form of:
%_; (hItem) ,
where hItem can be some different dictionary key name.
Close the file.
Note: This last step is necessary.
The absence of any characters in between the tilde "~" and the greater-than sign ">" indicates that the data is empty. Third-party plug-ins or other software cause hitem, because the entry is not native to Illustrator. If you find another name in place of "hitem," report it through Adobe's online bug reporting page:
