If you encounter a Server Error or DataReader error or GetDataReader, or invalid column name error, a common solution to this error is to be sure to apply the latest AdminCS update to Aeries. This will update your database with any updates to tables or fields that may be needed. In order for smooth operations, you must ALWAYS apply the AdminCS update right before you apply the Aeries Web update. These fatal error screens are sometimes referred to as a "Yellow Screen of Death" or "YSoD".
