Thanks Varun, but the procedure Bill suggested worked great.

Gary,
>>Error: flash NULL referenced in pad OB71X96NP could not be found.
Try this:
1. From "good" design, export "Shape and flash symbols" (File > Export >
Libraries)
2. Open "bad" design, click Setup > User Setup Preferences > Paths >
Library > psmpath > add path that contains the exported flash symbols
3. Click Apply > OK > exit Allegro
4. Re-launch Allegro and open the "bad" design
Regards,
Varun

Hi Gary,
Have you done: Tools > Padstack > Modify Design Padstack > Purge > All
If not, try that and then flash_convert again.
Let me know if the flash_convert.log still complains about unused pads.
