New info : with verison 1.0.9 sometimes if I use 192.168.xxx.xxx and I insert the pass the connection goes on and I can arrive to the desktop page of Airdroid.But if I use the adress web.airdroid.com the problem still remain.
Always on XP sp3 Chrome 21 and SGS3
Same happened to me as told in another thread.My smartphone is HTC One S , OS Windows 7 and browser Firefox latest version and Chrome 21.0.1180.75 nevermind which one I use as the new version version 1.0.9 does not work (counter stuck on 0 after inserting pass ).
Back to the previous version 1.0.8. it works fine (luckly as this is the most useful app for me)
Same problem here using a Galaxy s with CM 10 and chrome as say above just go in manage application and clear data for Airdroid (i clear application data and cache) thanks to gaetanoz
