I recently started Skyrim. At the start, I went with the Stormcloaks, when we were going to Riverwood, I went ahead of the man, going straight to Riverwood. I got there and I couldn't talk to his sister, I looked it up and I went straight to Whiterun and spoke to the Jarl.

That's not the problem though, my Navigation Bar at the top does not appear, nor does my health or stamina. I play on full screen at low quality. My friend says it's because I skipped that part of the 'tutorial', but everything else is OK.

Anyone know how I can get that back?
Thanks.

Refer to the instructions on http://www.uesp.net/wiki/Skyrim:Console on how to open and close the console
