I got the same "Unexpected attribute 'url' found in
'endpoint' from file: services-config.xml" error.
To resolve it you have to install the adobe Flex 2.0.1 Hotfix
2, that fixed the error.
By the way LCDS it's just FDS 2.51, but they changed the
name, it really doesn't matter...
Here's the link for Flex 2.0.1 Hotfix 2:
http://www.adobe.com/support/flex/ts/documents/flex2_hf2/FB2_Hotfix2_Installer_Win.exeThat's the Hotfix 2 updater installer but if you want only
the fixer, not all the updater installer, check on
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402000...but I resolved the problem using the full installer...
