I have bought a new computer and want to re-install the 747-400, 747-400F and 747-400X - but how???Having logged into my PMDG account, it shows all three downloads links as 'expired' and suggests contacting PMDG Technical Support. Found this on the PMDG website:"When you purchse your PMDG product, you receive 7 days of free download access. After 7 days, you may contact PMDG technical support and request to redownload your product. Within 24hrs* we will send you a renewed download link and you will be off and flying!" On the 'Contact PMDG' page, there is no mention of Technical Support, but there is a link called PMDG Product Support, which take me to a page called 'Support Desk'. Unfortunately, my PMDG log-in details aren't accepted.Finding this all very un-clear and frustrating. Hope you can help...Thanks,James Stevenson
