I can't open a new file

Question

hi, 
 
 I have just started to use trados studio 2014 and I watched the video. according to the video a translation panel should appear after I select the source document but i see only the title of the document, but not the content! I tried several times but it didn't work. Sometimes a conversation box appeared with a text like: conversation is unsuccesfull or something like that. why does it not work? 
 can anybody help me?

thank you very much Walter, but i sorted it out on my own. the problem was not about what i did/did not do. It was about the source document I was trying to upload. Studio did not recognize that type of pdf. so I change the format of the source file, and it worked!
