Query with jquery.min.js

Hi, I am very new to using jquery. I am trying to develop a gallery in lightbox which uses jquery.min.js. When testing in a browser the gallery works fine in Chrome but not in IE 8. When enabling the script debugging feature in IE  8 I get a message as follows: Error in line 120 character 165; invalid argument and the code f[b]=d is highlighted in yellow. Can anyone tell me what to do please? I am not familiar with java script. Is my copy of jquery.min.js corrupt? If so how can I easily download a replacement? Thanks in anticipation for any help.
