livezilla button hiding underneath other modules

[zonagolf]

I just started moving my shop to presta. Put a couple of items in the shop, everything worked great. I just addes the Livezilla chat service, installation went fine, but unless it is the only module on rightcolumblock it will hide underneath the other modules.

I am using the black and white theme, i tried to fix it but everything I tried failed.

shop address is http://zonagolf.com/prestashop

Thanks in advance!!!
