As this is primarily a customer-to-customer forums, you aren't going to get any direct help here, as far as someone logging into your account to "fix" it for you anyways.
That said, I've never personally installed Joomla! via the one-click installer, as I prefer the flexibility of doing a custom install, and therefore I can't help you I'm afraid
If you really feel it's an issue with the one-click or your account specifically, you can always contact support via the control panel. Otherwise, someone here might be able to help you better than I
