Restart client. Looks like a connection issue. If it persists, then I dunno.
Fix Steam for Windows – Reinstall Steam (Windows Programs & Features)?
Scrap my previous reply, as this is a steam store issue (not the software steam as it is technically web browser for the steampowered.com store) try restarting the client, computer, router all connection based things ass i believe this to be a network related issue
