Hello Colleen:
The message indicates that something went wrong during your most recent GL posting and there's a good chance that your GL data is damaged.
Did you see an error message during posting? Was there a power problem? Was there a LAN problem of any sort?
Next you should use Adagio to make a Backup and then run the Data Integrity Check process. Both processes will be quick.
If the Data Integrity Check says your data is damaged, you have 3 basic options at this point:
-Data Integrity Check may be able to resolve it (install 9.0B first as Michael suggests)
-Restoring from your most recent backup and re-doing your work
-Getting your data repaired by a professional.
If you choose to restore your GL data, check with your Adagio consultant to be certain that the right files are restored. If you choose a data repair, Softrak can do an excellent job but be aware that the cost starts (I think) at about $350.
