Can someone help me? It’s a really bad situation for me, I can not work with Rapidweaver. I need help about this error that happens when I click the Preview mode. Do you know what’s the cause?

In addition, on a project whit only Email stack on RW7 returns also this error: [![](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/2X/2/249a7d7f3d6d8b6145c3471d510a55e0a2faba29.png) ](https://dl.dropboxusercontent.com/s/hy5k3vkz1v0mnoy/Screenshot%202017-11-06%2014.13.13.png?dl=0) This errors may be due to the fact that some addons I have recovered them from the Time Machine backup disk and that the project files were from Rapidweaver 6? From when I installed RW7 I have more errors. Can someone help me to fix this serious problem?
