Vantage 8.0: Crystal Question

We modified the Aged Receivables Report by changing the formula for
days out (30, 60,90). We then added these versions as a new style
under the original Aged Receivables Report in the Report Style window.
The new reports displays, we can run it, but an error and a blank
window display.

Unknown Database Connector Error. Failed to retrieve data from the
database, Error in file C:\DOCUME~1\azuleger\LOCALS~1\Temp\AdgRcv30
{71803686-B9CD-4327-98EC-78608260A572}.rpt: Unknown Database Connector

Then the report window displays blank. Does anyone know how I can fix
this error?

Thanks in advance for your help!
