What symbols do I have access to with the ERT In-Count trial?

We started our ERT In Cloud trial today and I'm working through the sample applications. The samples request data for '/TRI.N'. I would like to specify more symbols as we start to test our feed handler work.

I've tried '/MSFT.O' (Microsoft) and was attempting to get data for the S&P E-Mini 500 by using 'ESU9' but both symbols came back with an access denied message (the 'user req to' portion changed for different symbols - let me know if you need those codes). For '/MSFT.O' I received:

RECEIVED on session1:
[
{
"ID":2,
"Key":{
"Name":"/MSFT.O",
"Service":"ELEKTRON_DD"
},
"State":{
"Code":"NotEntitled",
"Data":"Suspect",
"Stream":"Closed",
"Text":"Access Denied: User req to PE(5050)"
},
"Type":"Status"
}
]

Please let me know what data is available or if I'm just entering the symbols wrong. Thanks!
