But mine doesn't work. Perhaps the problem is, Google Chrome said:We’re announcing the end of Chrome’s support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple.(https://chrome.googleblog.com/2015/11/updates-to-chrome-platform-support.html)

It's exactly the same.

Also, I can not get reward even if I finish quests(I can only get quests from microsoft computers at my friend's house).
