Is there any way I can use sage if "manager" is in backup on another laptop?

SUGGESTED

I was using Sage at home and it was uploading/backing up to the cloud. Thought I had shut the computer down but obviously not as I now cannot use sage on the work laptop. Tried disconnecting from the internet to work offline but still get the error message that I am unable to as manager is backing up. Help please! I do not want to go all the way home :-( Thank you.
