It would really help if they posted where they downloaded it, the hash of the executable file, if they kept it on an online PC or offline.
We would investigate and help them out. But they usually never come back to comment.
those who don't come back usually have made a silly mistake. for example many don't let their wallet sync so they don't see their funds, then they think they have been robbed. when it is fixed they forget about everything and go away.
but it is also possible that they got if fixed elsewhere. there are other forums like reddit[1], there is Github[2], there is also an IRC channel[3] for Electrum. and when you fix it somewhere else you don't just go back to a random forum you visited once (bitcointalk) and update a topic you made with a throwaway account!
of course there is always an occasional troll too!
