Flash suddenly stopped working ( os x 10.6.8; Chrome 49)

Hi there! I'm using a pretty old Macbook, working on OS 10.6.8, so i'm using an older version of Chrome too (49.0.2623.86) . Up until this evening I've always used this Macbook for everything and it worked all well, even though it's old and uses outdated versions. I could open any website, watch any video, use any kind of videoplayers without a problem. Even today I watched videos and it worked fine.

Tonight I opened a news item video of yahoo news and all of a sudden it wouldn't play. Then I opened videos which I watched earlier in the day without any issues, but again, suddenly it doesnt work anymore. It says that Flash is blocked because it is outdated, the play icon on the video box is as usual but when I click on it it goes gray and shows a puzzle icon and says, flash plugin failed to load. Then it has two options:

Approve for once or update the plug in. If i click the first option, it doesnt do anything, if i click on update the plug in it takes me to Google Chrome help where they explain how to change your flash settings in Chrome and to turn flash on or update it or reinstall flash. But in my settings, flash is already turned on as -allow sites to run flash- .

When i try to reinstall flash, it installs, but everything is the same. Keeps giving me the blocked message.

Later on I again tried to watch the yahoo news item video, but now it just says video not available in your region, and doesnt say anything about flash anymore. But on other videos it still gives the message that flash is blocked.

What can I do? I am aware that I'm using an old Macbook and old version of Chrome, but it worked fine, even up untill a couple of hours ago, and now all of a sudden this happens. How come?
