Can you repeat the question please ?
There is this action user did. You just want to make sure he understands the consequences. So you craft up a nice little message box asking him to confirm the action and explaining what will happen.
Unfortunately, you forgot Steve Krug's advise : Once your text is ready, remove half the words. Then remove half the words again. Then remove half the words again. So your explanation is too long.
Even worst: you put your lengthy explanation after the question that user is supposed to answer. Then you added a lot of useless yet very distracting text such as complete version and build number displayed twice (!) , a link to message help (in addition to the already existing Help button).
Conclusion: Either user is scared and histerically tries to dismiss the dialog, whatever the consequences. Or (s)he carefully reads your prose to figure what you want but then by the time he's done reading the text, he doesn't remember what the question was.

In this case, I even had to read it 3 times to realize there IS a question ! But OK, maybe it's only me...
