Good program (not for Windows XP)

For many years I use to create my tax return the QuickSteuer Deluxe with great satisfaction.
Unfortunately, the current version 2015 (ie for the tax year 2014) is no longer suitable for Windows XP, resulting in a switch to the unloved WIndows 8.1 necessitated for me.
Installation of the program was easy as usual; However, the operation (surface), in my view, to the detriment.
By switching to Windows 8.1 (of course new computer) I am not so far managed to transfer the stored basic data from the previous year.
