Error in log, what does it mean?

Hi,

Error:

Type 'ZennoLab.ZennoPoster.Modules.TemplateExecutor.ProjectExecutors.ProjectExecutor' in assembly 'ProjectMaker, Version=5.9.9.1, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

I just formatted and reinstalled windows and now I have this error when trying to run a project-in-project.
I have .net installed and activated.

Thanks in advance

Ok nevermind, I copied my main template from my external harddrive to my main C:\ and it worked...
