I have a surface pro that I have had for a few years. Last year my daughter used it for school. When I signed her out of MS Office, it now say it is unlicensed, I had purchased Office when I originally got the surface pro. There is no license stickers on the outside. It had worked fine for years till she had to add her account and the tools for the Public School account, not that I removed her, it appears to have changed something and Office no loner is activated.
How do I recover what was already purchased?
