Failed to show file transfers on desktop app

I regularly share some hyperlinks and files from my Android cellphone with my PC via the AirDroid Windows 8.1 desktop application. Since a few days ago, I am unable to see these on the desktop app (second icon from the top left bar): it just shown the rotating circle as if synchronizing, but nothing happens. I did also check the web app, but coulnd't find my shares there either.
It was working just fine last week and I did no change no any of the apps. I tried login out and in again on all devices, but this didn't solve the problem. It looks like some kind of programming bug or some server being down. Please help.

I'm having the same problem. Hope someone can offer a solution.

Can you send a screenshot of this?

And please also attach the logs and exceptions to help us troubleshoot.

How to get logs and exceptions

Create a file named log.dll in application support/airdroid/ Open AirDroid and log in. And then Click Finder > click Go > Press Alt until Library shows > Click Library.
