    Does taking the battery off the charger allow you to write? It may be protecting the system from a high output charge.

    There is a new beta for that issue. Just had the same issue with a 2007 Canyon 2.9.

    Fixed in the newest beta, email support
    It doesn't have to be perfect, it just needs to be done in two weeks...
