help, 569 session exception

Hi, I have a problem with store on Sencha Architect 3.

first think: I use test network, on this network I haven't internet access (maybe this is the problem).

now the explanation about the problem.

0- controll Url prefix, this: http://domain:7040/desktop/examples/P01 (maybe this is wrong, P01== project name)

1 - Create the "devtoken" (correct)

2 - execute test RPG call - The data is correct, but i can't download (XDC MODEL), when i click on download button, don't download.

3 - copy manually all content (XDC MODEL) to plain file, and change extension to xdc. (correct?)

4 - Import on sencha ARchitect (edit->import content) - (correct)

5 - drag to model - (correct)

6 - create a store and use previous model.

7 - load data (right button), and now, the fail 569 session exception
