Sometimes, when I try to install a newly-released game demo on Steam, clicking the "Download Demo" button in the store page, from the built-in Steam browser, just does nothing - the only thing which is happening is the the mouse cursor momentarily changes from a link pointer to a regular arrow.
If I go to the store page from outside Steam and click the "download demo" button, it correctly prompts me to open Steam - but then it does nothing as well.
This has happened for me more than once, with more than one demo; but other demos download, install and run just fine. Can anyone provide a solution?
OS is Windows 7 64 bit.
