As a good illustration of my current level: my previous post was lost and failed because I suddenly seemed logged out.
Brief recap:
I am doing this (following the very clear guide on help.hana.ondemand.com)
Connecting to SAP HANA Databases via the Eclipse IDE
I can't connect!
Enter your account name (? .. maybe p*********trial), e-mail or SCN user name (P**********), and SCN password ( is this my sap/hana password???).
I feel bad that I can't even complete this step.
