You almost certainly have two versions of Flash running at the same time. They tend to trip over each other. I know; I've suffered from that same problem myself. Here's the problem: Chrome comes with its own version of Flash. In addition, you may have another Flash installation, downloaded from Adobe or bundled with your computer. The trick is to turn one of them off. To do that, click Chrome's address bar (where you type a URL) and type chrome://plugins. This brings you to Chrome's Plug-in page. Take a look at the listing for Adobe Flash Player. If it says "(2 files)" right after the name, there's your problem. Click the Details link near the upper-right corner of the browser window. You'll see two .dll files listed, each with a considerable amount of information, most of which you can ignore. You can see which Chrome is which by checking the location field. Chrome's built-in version will be in your Appdata Chrome folder. The path will look something like C:\Users\yourlogon\AppData\Local\Google\Chrome\User Data\PepperFlash\11.9.900.117\pepflashplayer.dll. Adobe's version will be in the Windows folder. The path will be something like C:\Windows\SysWOW64\Macromed\Flash\NPSWF32_11_9_900_117.dll. Each of them has a Disable link, and you need to click one of those. But which one? As near as I can tell, it doesn't matter. I disabled Adobe's. So far, no problems. If this fix doesn't work for you, uninstall and reinstall Flash. If that doesn't work, try disabling some extensions and see if that helps. To do that, go to chrome://settings, and click on Extensions on the left.
