have v17
bought v18 last august (never unpacked it)
I have been out of the country 8 of the last 10 months
and did not install v18
(as did not want to break anything working)
when I ran the installer, it asked for the Ser# on my purchase email
well - I have ALL my emails for the last 30+ years
and there is no new ID from XARA or MAGIX

I tried to use the serial number from 17
and it was denied as too old

any suggestions?? or am I out the $100
