This isn't uncommon for sites that sniff adblockers too, though it varies how much of an obstacle it is. Often you can Inspect the div they are covering things up with and just delete it (or block it for good with uBlock etc.) - clever implementations won't fetch the actual content you wanted to read, so you'll only uncover an empty page, though.
Did you already have cookies installed? I found that if I let it load a cookie then block it, it would load (but it already had a cookie on there, defeating the point). Try clearing out everything (or try on IE)
