I will be out of office from January the 17th to the 26th. For order issues, lost licenses etc please email orders@fastspring.com and quote your order number.
For download issues, please read the help, specifically Troubleshooting Downloads at http://www.mac-dive.com/help. Most likely your problem is solved in there. If you are still having trouble then feel free to drop me an email. I hope to have internet access but responses may be delayed.
Cheers, and apologies for any inconvenience!
