I've started working with Adobe flex and have copied the code from "Creating a Flex Mashup on Force.com" (found on this page: http://wiki.developerforce.com/index.php/Creating_a_Flex_Mashup_on_Force.com) in its entirety.

I've also tried the two other example provided by Salesforce on this page: http://wiki.developerforce.com/index.php/Getting_Started_with_the_Force.com_Toolkit_for_Adobe_AIR_and_Flex.

When I run the second sample i get these messages in the console: 

[SWF] demo.swf - 1,551,229 bytes after decompression

offline but we will succeed at logging in anyways

query - offline

SQLError: 'Error #3115: SQL Error.', details:'no such table: 'Contact'', operation:'execute', detailID:'2013'

Select Id, FirstName, LastName FROM `Contact`;

SQLError: 'Error #3115: SQL Error.', details:'no such table: 'Contact'', operation:'execute', detailID:'2013'

Select Id, FirstName, LastName FROM `Contact`;

It seems to imply that I'm off line, but I'm not.

In any event, it appears that I am unable to login in either case.

Does anyone have any idea of what might be going wrong?

Thanks for your help.
