Hello Jim
I have the same problem, but my limit is 21 columns. I think the limit is caused by the DataReader SchemaTable. Check the following value:
IDataReader.GetSchemaTable().Columns.Count
Columns in the SchemaTable are Metadata (ColumnName, ColumnSize, DataType, AllowDBNull...), the columns that are selected with the DataReader are stored in the SchemaTable Rows Property.
For Oracle and SQLServer i used this workaround:
DataTable dataTable = IDataReader.GetSchemaTable();
while (dataTable.Columns.Count < dataTable.Rows.Count)
    dataTable.Columns.Add("Dummy" + dataTable.Columns.Count.ToString(), typeof(bool));
I think developpers of CR use the Columns.Count instead of Rows.Count property when getting the data out of the DataReader.

Walter
