Below is WGT response to my reported problem:
Thank you for the message. Please note the videos for free credits are region based and if you are not able to view videos it means that there currently are no videos available for your region at this time. The 3rd party that hosts these videos typically has new videos available every 1-2 weeks.
My response was: This has been going on for months.
There is another thread about the same problem dated 11-28-14. I guess the "Turd" party doesn't know they typically have new videos available every 1 - 2 weeks.
