Often customers try to fix the problems themselves by trying various things that come to mind. This is great.
Unfortunately, what tends to happen is that customers get frustrated and post messages something like:

The very next message from tech support looks like the following (I think they should have a standard template for it, myself):
Can you describe what you mean by “doesn't work”? Do you mean
