compiling process ends with an error

  • I hope someone could help me. First I have to say that I have TexStudio till 2
    days so I'm really not an expert. But here is my problem: All time I want to
    compile my code to PDF the programm runs but at the end there is a message
    like: "process ends with an error" but neither the log-file nor the error-
    message shows me the error. I really don't know what to. It woud be great if
    someone could tell me what I've to do.

    - TexStudio 2.3
    - MiKTeX 2.9 (with the latest updates)
    - Win 7 64-bit
