Welcome to Windows Seven Forums.

You could try asking Microsoft Support as something is very obviously wrong with the activation process.

Yes i contacted microsoft and they couldn't help so did a full system reinstall. 6 hours later everything back and office running fine.

Pleased to hear it.

We can only assume the original Microsoft Office installation was corrupted in some way.
