STOP 0x00000050 in Error Message in Atmfd.dll When You Use Type 1 Fonts

This article has been archived. It is offered "as is" and will no longer be updated.
During the rendering of an Adobe PDF document, you may receive the following error message in Atmfd.dll:
0x00000050 (0xf0009ed5, 0x00000000, 0xbee02ab3, 0x00000002)
This behavior occurs because a null pointer is returned when you use an Adobe Type 1 font that contains a data structure that is not valid. A null pointer may be returned with valid fonts, but in such cases the computer is under high stress. The high stress causes a synchronization problem between the asynchronous transfer mode (ATM) font cache and the current thread that is trying to access a font that has been removed from the cache.

After you install the update, the Adobe Font Manager may not load a font that is corrupted or has a data structure that is not valid. When you use the built-in font manager to preview a font that you think may be corrupted, you may receive the following error message when you try to preview the font:
Error: The requested file c:\winnt\Fonts\Font Name. PFM|c:\winnt\Fonts\Font Name. PFB was not a valid font file.
