Tip - Backup all your files! - Tech support is notoriously bad about this -
you might be lucky but it will probably take a while for them to make
absolutely sure your not using a pirated version.
It *will* get sorted out but in the mean time you should probably download a
Linux livecd or something so you can keep working on your computer whilst you
wait for your new key. These are quite useful for rescuing systems that have
gone down - they boot into the computers memory so they don't touch your hard
disk, but atleast it means you can keep working. You can probaby pick one up
- check the forums if you need any help.
