Sorry but I need a little bit more information... There could be many possibilities as to why you can't watch videos. For example, your region, bad connection, devices your using to watch, what show, etc. If this problem is still occurring now, I suggest you contact the Viki Staff by submitting a request (2nd button: Home . Submit a request. Check your existing requests).** Be sure to include:**
-your region (country).
-what device your trying to watch with (if necessary tell them what browser you use, Internet Explorer, Google Chrome, Mozilla, etc.)
-What show were you trying to watch.
-When did this start and is it still limiting you from watching any show on Viki today.
-If possible, show a screenshot on when it started, (for example; take a screenshot of when you start to watch a video, and if it still doesn't show for more than 30 minutes, take another screenshot, to show that after 30 (+) minutes, it still didn't move.
I hope this helped!
