Authorization Error for ODATA Service

Hi Experts,

I have created trial account and using odata service to expose my own table.

Its working fine in browser for $metadata.

But when i am trying to see content of my table , getting error as

exception 1: no.71000258 (ptime/query/checker/query_check.cc:2422) Not authorized NO exception throw location recorded. Stack generation suppressed.

Is this the problem due to trial account ?

or

something can be done to resolve this ?

Kindly let me know ....

Thanks in advance.
