The box, mara- fix is not working for me, either - the actual issue is at the end of the servers deploying the Virus database signatures (unlike Retail Users, the Trial Users are the last one to receive it.)

I Just done a clean install in VM box, mara- fix and it updated fine maybe they need to reinstall it to get it working again , on weekends there's not many updates so servers should not be overloaded . But using a key on my real system Ive got every update so far.
