Those, who are using Chrome as their preferred browser might have trouble loading the Reports section because of Flash being disabled by the browser.
To allow chrome for LiveAgent you can either go to Chrome settings here: chrome://settings/content/flash and add a new page to the Allow section in the following format:
[*.]ladesk.com
An alternative way is to go click the "i" circle in the URL field of Chrome next to https/http and Allow Flash from there.
