Licensing Error with XenApp EVA Package

Hi,
Recently, I downloaded XenApp EVA package and successfully installed it according to its manual. However, I am getting license error on the CTXS-XA1 server. I already did some re-installation to get a new license but I am not allowed to request the same license files. And also, I logged in as the administrator and try to run the Streaming App, and got no replies.
How can I fix it? I posted the errors I am facing.

Cannot acquire a MPS_PLT_CCU license. The required license is not installed.
Citrix Password Manager is disabled.

The licenses required by this edition of Citrix Presentati

Citrix XenApp could not contact the server. Please check your network connection.
