When I try to do anything with modeller9.10, an error menssage occurs with "C:\Program Files (x86)\Modeller9.10\modlib\modeller\__init__.py" line 51 and I canīt  import "os" from "C:\Program Files (x86)\lib\os.py" line 106.

Please, could you help me fix this bug?

I have read the release notes, but I still could not fix the error. Could you teach me step by step?

All the best,

Bruno Madio
