Here is an URL to one of the video sources (hosted on Vimeo) – the “Synchronizing” tutorial. If you can see this video correctly in a browser, then you probably have an issue with the DEVONthink installation. If not, then you’ll want to reinstall whatever it was you trashed or uninstalled. (Like, the Adobe flash player.)
Vimeo played fine. So, I hate to ask such a question but, what should I do next, reinstall the software? If so, is there a deinstall or how do I go about doing this?
Vimeo versions of the video tutorials play here without Flash Player installed. As a workaround, if you’re still stuck and don’t need Flash outside a browser, you could:
• Uninstall the Flash Player plugin again
• Watch Vimeo versions of the tutorials
• Use Chrome (with its bundled FP plugin) when you need Flash access inside a browser
That’s my permanent way of dealing with Flash here since I prefer avoiding it as much as possible.
