Sounds like you have something "Auto set" that clears cache on a daily basis. Go to google (Chrome tools) and fix your preferences. You may have browser set to clear cache each time you close browser. You'll find your settings in "Under the Hood" in "options".. It's that wrench at top right. When you get to "Under the Hood" click "Content setting" and make sure it's NOT set to "clear cookies and other site data when I close browser"...need to put it on "Allow site data to be stored".

P.S. Something else I think is nice...Open a new tab beside your existing...type in about:plugins it will show you all of them and show if any need updated including your flash version. You have the option to enable / disable...so you can download multiple flash versions...enable one of them ...try it...go back disable that version...try another and so on and see which version runs better for you. Pretty cool.
