Hello, I'm trying to test the Eikon Data API. I've got a username and a password for a two week access to the Eikon Program. I've gone through the quick start guide for windows. I have the TR Eikon AP running, I've generated a key with the app key generator, i've installed the python eikon libraries and am now trying to run the following code with python 3.7:

import eikon as ek
response = ek.set_app_key('app key from app key generator ')
df = ek.get_timeseries(["BUR.L"], start_date="2018-01-01", end_date="2018-01-10")

The last line fails with the following error message: "Error code 403 | Client Error: Your Eikon account is not allowed to run Eikon API Proxy. - Your Eikon account is not allowed to run Eikon API Proxy."

Have I not got access to the API, or am I doing something wrong? Thank you for any help.
