My nodes can't be on publish state

Hi,
I've tested this module and it's works great ;)
The module Uc_node_checkout does not correspond completely to my needs.
Because I can't create products with more than 1 quantity.
So I'm testing with ubercart_userpoints module rules.
To use uc_node_publish I must remove the publication of content type.
But if I setting the type of content to be published, when I create a node, the content didn't published.I tried disabling the module, the uninstall also, but the content is not yet published
I thinks it's a problem with uc_node_publish because I can create another content type.
And theres content type didn't use uc_node_publish...
Do you have an idea ?
Thanks by advance for your help
Bye
