If you have a good internet connection you should be able to use the CD version of the software.
Unfortunately, you would not be able to connect with us from Korea, as our phone support is for Canada only.
So uninstall the software you have installed and reinstall using this link, make sure you are selecting the same software you have already purchased and use the IKC provided in the box from your original purchase.
Alternately, you can connect to our website (top right corner - "Sign In") and start your tax return online.
You will have to print(online version)(downloaded version) and mail to the CRA as well.
Good luck!
