hi, can somebody help?

i was working on a stroke applying different brush styles to it to see
which would work best. in the end, i decided to remove and delete a
brush style from the stroke, and go with something else. That is when
illustrator gave me a PARM error of some sort. I tried to save, but
couldn't. i also had photoshop open at the time, so I closed it, but
when I did that, the illustrator file began saving.


Now when I go back to open the file, it gives me the following error :


Can't open the illustration. The illustration contains an illegal
operand.

Offending operator: ";"
Context:
0 XR
1 0 Xd
/Def ;
(StrikeStyle),
/GObjRef : (Pattern Brush 4) (Adobe PatternOnPath Brush Tool)
/PluginObject ;


any suggestions? I have no backup.
