If your Support: Product Knowledge Base: My Account: Questions list shows no questions, it's safe to assume it was not successfully submitted.
I'm not aware of any recent problems with it, and given the number of submissions we recieve on a daily basis from the Web form, it would appear that if you're having an issue it's something related to your environment.
If it persists, phone support might be an option, or maybe trying a different computer or adjusting your security settings or something on that PC to see if it matters.
