Hi strikingknife,

 

Please try this way.

 

1.  Download the package below.

2.  Delete files "CuteChat.dll", "CuteChat.AppCode.dll" ,"CuteChat.lic"  and "CuteMessenger.lic" in the "bin" folder of your SharePoint site. And use the new one in the download package.

 

3. Delete folder "CuteSoft_Client" and use the new one in the download package and try again.

 

Keep me posted.
