Another tip: Give a thread at least 24 hours. Some folks only visit the forums once a day. "Bumping" a thread after only a few hours can annoy some folks.
Quoted from LTG:Keep the problem clear. Even if you caused it. So you don't get lots of answers that will vary and not help you fix your game.
Another good point--we don't care if you caused the problem or not. It happens. Plenty of techs will tell you about all the stupid stuff they did when they were learning how to repair games. Sometimes they were expensive lessons. Either way, don't be coy about anything you think you may have done to cause the issue. It may lead to an important clue that will quickly help find where the actual problem is.
