Many environments will not allow you to connect out on port 80, or will clip out XML data from these requests/responses. The easiest way to check for this is to open a browser on the machine running the sample code. In your browser, navigate to:

https://trial.serviceobjects.com/ain/

AIUS - Service Reference

Then try to run one of the operations with your trial key. If you get a browser error, or get no data back, then the sample code isn't able to connect either. Contact your systems administrator to resolve why you are not able to connect to Service Objects.

As a general rule, you won't get a field longer than 80 characters.
