I should clarify the error message:
The software successfully creates the shape file, however, the attribute table contains only zero values.
Thanks in advance,

Hi All,
I have used the AS Alchemist and I too like the interface. I was not able to successfully create census tract or blockgroup results.
I was wondering if someone else has experienced this and was able to work around it.

Hi, all
If you are frustrated by getting the ACS 5-year block group level data via Census Bureau ftpsite or DataFerrett, ACS Alchemist may be a good alternative.
I just tested ACS Achemist that was developed by Azavea & Temple University and I think it's easy to use. But keep in mind that only ACS 2005-2009 and ACS 2006-2010 data are available in the ACS Alchemist. If you are looking for 1-year or 3-year data, you still need Census Bureau data access tools including American Fact finder and DataFerrett.
ACS Achemist is an open source tool that enables the extraction of ACS 2005-2009 and ACS 2006-2010 data on different level of geographic aggregation, i.e., counties, county sub-division, tracts, blockgroups, etc. . The user interface is very straightforward and is a simple step-by-step process. The thing I like most is that output is saved as the shapefile and you can process your data in the GIS. The think I like least is that uses will have to create a variable file to define which data they want to get. The sample of a variable file can be find in the readme document which is included in the software installation package, but I attached one here for your convenience.
Here is the link to the ACS Alchemist home page:
