If I understand this well, you do not need to export/import your list. Your 2006 Simply data files are *.sdb and *.sdw (* = your filename).
Just copy these 2 files from their present location to a CD or USB Key and then copy back on your new computer.
I suppose you have installed SA on the new PC, so then you would be able to continue working after copying the data files (SDB & SDW).
Hope this helps.
