Javascript Error PunBO

Hi,

Hopefully someone can help me out..

I know that this is not the support board for PunBO but I was hoping someone may have seen and/or resolved a similar issue.

I recently installed PunBO integrated with Joomla! 1.0.12 Stable. When I click the Login Link in IE7, I get the following Javascript Error Message:

Line: 159
Character: 1
Code: 0
Error Message: 'document.getElementById(...).req_username' is null or not an object
URL: http://localhost/cms/index.php?option=com_punbo&Itemid=33&task=login

I'm not very savvy with Javascript. I've searched some of the PHP files and the .js file in the import folder but I still don't know where to begin to look in order to fix this error.

Thanks for reading...
