Amazing Laptop you have there
Wish I had something like that to use for University.
Since the Laptop is brand new, used for only 2 weeks, could be that you're missing some drivers and essentials, eg. NET Framework (not saying it is required to run DKonline).
You should run Windows Update a couple of times and let it grab anything it believes that has to be installed/updated.
Also, since it is a brand new laptop, could it be that you're using Windows 8?
