My email confirming the purchase gave me an activation code.
When I tried to enter the code (copying and pasting from the email) - it was an error meesage "activation unsuccessful .." so an invalid activation code.
I uninstalled the trial version and reinstalled it again.
I notice in this forum that this was a problem back in August 2009 and September 2008.
Looks like I'll be phoning Corel Australia tomorrow morning
Thanks
