Recently, my XPS10 tablet went through an update process that failed. In the process, the Microsoft Office product key code disappeared. Now I cannot access any of the Office applications. Unfortunately, I cannot find the manuals (2 years old) that might contain the code. 

A call to Dell tech support took over an hour just to be told that I would have to purchase a new Office suite from Microsoft to get a new key code. 

Any suggestions or has anyone else experienced this problem?
