We have created a couple of universe in IDT but we are not able to see them

We are on version 1.5.2 and we have created universe but when we select data sources we do not see them. I added <IP> <fully-qualified host name of BI platform> <host name of BI platform> to my pc host file but I was still not able to see them.  We have checked the services and they are all running.  What steps on config or process have we missed. 

Thanks
