Microsoft is planning to do a major overhaul with how IE renders websites and a preview edition is available on Windows 10 with the new functionality trickling down on a select basis (you are allow to enable it early though). Cheat Happens does not load with this new technology when logged in. Current workaround is to use another browser.
Behavior shows the site loads normally logged off and you can browse around the site and view forum posts or window shop trainers. Upon a successful log in, the page seems to never load anything beyond the banner. No idea the cause behind it or if I'm stupid and can't internet.
A defect report was logged to Microsoft for them to take a look at it.
Microsoft blogged about the new changes here for the interested:
