Can you please let us know when you have registered the module, did you specify version number? This field should be omitted. Please try the following:
1) Make sure that your products assembly is located in the bin folder.
2) Go to ~/App_Data/Sitefinity/Configurations/SystemConfig.config and delete the version attribute for your module.
3) Make sure that the resource class attribute is properly set (it contains the namespace of the class).
4) Restart the application.
