Version 8

I have had to reinstall following upgrade of motherboard processor and operating system.

When I tried to reinstall X5 V8 it asked for an unlock code which your system generated.

I don't know if I should have deactivated my previous instalation, you don't always think of these things at the time.

Should I (can I?) delete the now defunct activation key in "My Licences"?  If I need to transfer in future what is the correct procedure please?

Regards
