Enable form in the plugin - The fluid file was not found

Hi,

I’ve just inherited a project in Neos that I need to complete/extend. It’s using custom nodeType groups and all core nodeTypes are modified.
The problem is that it doesn’t have Form node type enabled, and I need to add it. After some modifications to code I’ve successfully manage to get form to the custom nodeType group, but when I want to add it to the page I receive following error:

The fluid file “resource://Project.name/Private/Templates/NodeTypes/Form.html” was not found.

I’m stuck here, and I can’t display default Neos.Form.
Any help would be much appreciated.

Thank you.
