Flash Player doesn't work consistently after installation on Mac

Hello,

I'm using a Macbook Air with OS X Yosemite and the Player appears to not work. More specifically it looks like the video is going to load but it either crashes while loading or just doesn't load at all. I've tried changing the settings to the recommended and doing a clean uninstall and reinstall. I've also used both Google Chrome and Safari but I still get similar results. Very infrequently the player will work after refreshing the page upwards of 10 times but as you can imagine this is problematic when wanting to watch something live. Also I have Flash Player 16 installed which is the most up to date I can have on my system. I've also tried to clear the cache of both, Chrome and the Macromedia and Adobe files on my Mac but still have failure. It can't be the websites I'm trying to access because friends have accessed the same sites without any problems while using the same browser.  This is most problematic because the thing I most want to use Flash Player for are subscription base therefore I feel like at this moment I'm wasting my money.

Thanks for the help
