HTC Desire 530 not running Flash

Hi, I have just purchased HTC Desire 530 and have tried to launch videos that require Adobe Flash 10. Error messages are "Network error" and "your device does not support Flash". I contacted HTC who assured me that Flash is on the Device and should launch, but the videos wont launch. I have downloaded it from Play Store, but it still doesn't work.

Anyone any ideas?

Thanks,D
