DOA X Client Datasets - Problems ?????

I am an user of Client Dataset/Providers for a long time (with BDE and Interbase) and everything works fine.

I sent you the same project in two ways: two tiers and web services(SOAP).

I don't think we received anything. Did you send it to support@allroundautomations.com?

It was post again.
Please check if you really receive it and tell me.
I post to support@allroundautomations.com

Believe it or not, we still have not received anything from you by e-mail, even though the e-mail address you specified is correct.

I did receive a demo project from Natalie though (6th post from above).

Do you have any other alternative e-mail ?
With this example I believe that will be so easy to see the problem.
