All-In-One Cufon not working in subdomain of wordpress 3.0.1

I am using the plugin All-In-One Cufon 1.1.0. in my site made of wordpress 3.0.1. As I activate the plugin though network (network activate) we found that this plugin is working within the main domain but it is not working in my sub domains. From my sub domains admin pannel though I place the Cufon code but it is not appearing. I wonder how can I use this plugin throughout my site?

Is the plugin not compatible with wordpress mu feature?
