Invalid root Flex ColdFusion Flash remoting

[Guest]

Hi there.

Please I know how to configure. Flex with CF 8 and CF 9.

But with CF 10, i get an error "Invalid root, when I use the project wizard from Flex 4.x

I do need help. I tried to create the project but I get the error.

It shoudl be exactly the same.  I have had no issues with Flex and CF10.  That being said I have not created new Flex apps for a long time and the only work has been maintenance.
