OK. here are the steps to take:
1. backup the reg.txt file.
2. delete ALL games in attac. click on game, click delete.
3. delete the attac directory complete
4. reinstall attac
5. copy the reg.txt file to the datafiles directory under attac.
6. start attac.
7. make sure to create the game properly. it sounds like it is not created.

8. restart attac.
that should fix it. either the download was corrupted or some datafiles are unhappy moving to the new version.
