Ok, i bought rc4 some time ago, got a key, all worked fine.Yesterday i formatted my pc, reinstalled fs9 and all my addons including rc4. Requested a new product key. Received it 20 hours or so later, when i enter it into rc4, after a few seconds delay, rc4 closes. When i start it again, it asks for the key again.Now i have tried to contact the help email (around 6-7 hours ago) with no reply, so im taking my chances that the support on here will be a little quicker......................

can ignore this, finally got a reply, and a working keyThanks Rick :)
