I was beginning to think that I was the only one with this same problem. I have had the same thing happen with both PAF 4 & 5. I have spent many months and countless hours trying to print an acceptable ahnentafel and/or modified register report, but I've had no success. I've been in touch with the LDS tech support and they could not help me as they could not duplicate the errors. I have also downloaded and installed PAF several times which does not correct anything. I hope you have better luck that I have had.
