Hi MarjaR, We have fixed the silverlight 5 issue, please download the latest version and try again. Latest version download url: http://www.cutesoft.net/downloads/folders/44395/download.aspx Regards, Ken 

Senthil,   Does your 64bit PC install the Flash > (and the Flash version?) ?   How about click on the Silverlight column buttons ?   Regards, Terry

Hello?, Any idea to solve the problem?

Sorry the error message that shows is:- Silverlight: The upload task is interrupted!WebException :UnknownError,[HttpWebRequest_WebException_RemoteServer]  Arguments: NotFoundDebugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. 

Hi, now it works completly  for firefox (Silverlight and Flash). But for Opera i still get the same message on flash mode. Uploading with silverlight mode works for opera, but i lose my customized browse button style.

I understand.   However it's impossible to have selecting multiple files feature by default. The clients need to install Silverlight or Flash to have this feature.

Hi d6Hemant,   The HMLT5 is the best option for it, so we have set it to the default upload type. Then silverlight-->flash-->IFrame.   Regards,   Ken 

I had this same issue. In my case I found that Silverlight was conflicitng with JQuery. Using your solution corrected the issue. Also disabling JQuery worked as well.  Dana 

The issue is reproduced when uploading files > 100kb

Marv,   It seems that the firebug have bug working with the Flash/Silverlight.   That's a good news that the new firebug have fix the issue.   Regards, Terry
