Crystal Reports Error.

This error is usually a result of corrupt or missing fonts on the workstation.

Solution:

1. Make sure the Letter Gothic fonts are installed.  Check the Fonts folder in the windows Control Panel. If they are not installed, they will need to be copied over from another computer and installed using the font installer ( accessed from the fonts folder -> file menu)

2. If the fonts are installed but preview blank when double clicked on, they are corrupt. Delete the fonts from the folder, reboot your computer and reinstall the fonts. you may have to reboot your computer again after installing the fonts.

3. There is a possibility that the fonts folder is corrupt and must be repaired. You can download the TweakUI utility from Microsoft's website and run the Fix Fonts option under  the Repair section of the utility.
