To be clear, I know nothing about this package, but the following may
be helpful for those who do:

1. What exacty was the error message that you received? Or was it a
warning? "cannot read" may be too vague to allow others to respond.

2. ?maintainer to find the package maintainer. It may be necessary to
contact them directly with the problem.
