You don't have to export anything from CrazyTalk 7. The files are already stored in the correct format.
So for example, if you have saved a custom script in CrazyTalk 7, you would just select "Create Script > CrazyTalk Script" in CTA2 and then navigate to the folder below which is where all your custom CrazyTalk 7 scripts will be saved. The files will have the .ct7script extension. Just select one to load it.
C:\Users\Public\Documents\Reallusion\Custom\CrazyTalk7 Custom\Voice Script\
