Hi Duffys
That is a serious error message. You should restore from a recent backup if you have one. If you don't have one, your options are not as great.
1) You can send out your data to get repaired by a data repair company. Softrak Systems is one.
2) You can restore the GL from a not so recent backup, and then re-enter the missing entries.
There are other options, but they are more complicated.
If you have an Adagio consultant, this is the time to call him or her. If you don't have one, look one up in your area.
