troubles with DJ-Catalog2 extension

Hi all,

i'm using your nice template for a customer.
i use also the DJ-Catalog2 component + module from http://dj-extensions.com/extensions/dj-catalog2.html

i try the mod_djcfrontpage module on my homepage
When i use IE 8 or IE9, all is OK, no display trouble
When i use Firefox or Chrome, the "read more" button is pushed on the left and not usable.

is there any solution ?
the developer told me there is a trouble with your template.css file ...

Thanks
Regards

JP
