Susana,
I’ve read your post a few times but don’t think I have enough information to diagnose it. Can you add the information requested in the “Posting Guidelines” announcement in this forum for us? That will at least narrow down the possibilities.
Another thing to check is whether or not any messages have been written to the Eclipse log file, located at <workspace>/.metadata/.log. I’m also a little unclear what you mean by
since when I open the dialog box for deploy, the push buttons for adding a server never are available
In addition to the followup information, if you could email a gif or jpeg screenshot to support@genuitec.com and reference this thread it would help us “see what you’re seeing”. With all that, we’ll definately be able to figure this out and get you up and running.
