If you've reinstalled 'Crystal Reports for Adagio' on your workstation, you should re-do the workstation setup for Adagio programs on your workstation afterwards. You may even need to reinstall the Adagio programs AR and IN themselves. This is to update report table and system information.

Perhaps you have 'C:\windows\crystal' instead of 'C:\winnt\crystal'? Or your WINNT directory is hidden when you browse through Windows Explorer?
