Help! Error message and corrupt files
I'm working with Adobe CS6 (64 bit) on a work computer. I've created two files (separately from each other, no cutting and pasting between files etc.) and both are coming up with the error message below when I try and reopen the file. I'm not a super technical person but have been using Illustrator for years and have never come across this problem, I've no idea how to fix it. My IT department are able to restore previous versions of files but inevitably these don't contain all the content, and I'm wondering if I can identify what the root cause is so that I can stop it from continually happening - what am I doing wrong?! From looking at the error message it seems maybe its a particular symbol that is causing the problem? I am using a free symbol library from IAN website.
I really need to be able to use Illustrator to complete my job but it seems every file I create gets corrupted which is not helpful! There seem to be heaps of threads with illegal operand questions but none really match up so don't make much sense to me?
Any ideas?
