Dear Christopher G Mayne,

I am getting the same error as Wenhao and Esra Bozkurt while running charge optimization:

I read your suggestion to Wenhao [cd to a local directory in which you have read/write privileges, and rerun the optimization.] I was already in the directory which contains all files concerning ffTK on my own P.C.

Sincerely Yours,
