Could not find Dynamips. 3.0.2 (pip)

[bs0c]

I updated from 2.2.52 (system) to 3.0.2 (pip).
When I open my old projects and I have got: Could not find Dynamips in all my projects. OK

When I have tried to open projects with old version. It has told me: Oh man... your projects now belong to version 3.0.2, go there and now forget about me. OK

I have tried to repeat my old project. Add some dynamips images. I made something, and closed it, and opened it again. And now I have: Could not find Dynamips. The second time: Dynamips identifier 2 is already used by another router.

Console:

@bs0c how have you fixed your problem? thanks.

I thought gns3(pip) included dynamips and ubridge. So I have removed gns3 (system) and its dependencies before using it.
