Well, first we try the standard stuff:
1. Hold Shift key and click Refresh button in browser
2. Clear your browser's cache, then restart browser and try again
3. Try a different browser (this can help narrow it down to an add-on or a problem with a specific browser)
4. Make sure your security software is not blocking SOTT. Recently, we had someone who had problems with SOTT, and for some reason, Microsoft Security Essentials was screwing things up.
