"It doesn't work" is a really low quality way to ask for help.

What's the observed behavior? What's the expected behavior? How can I reproduce it? Can it be captured in a screenshot? Is the problem captured in a log file? Include all that stuff.

Yes, it takes more time to put that kind of a report together, but doing that up front makes figuring out what you're talking about and resolving the problem go a lot faster.

Otherwise, expect a lot of "works for me" and "can't reproduce".
