Did you put the official license in place?
The license file should be in the bin folder along with CuteChat.dll. There should already be a .lic file, replace the one with your official one. Or do a file search for CuteChat.lic to see how many copies there are. Replace all those which are within the install folder of Cute Live Support.
If still can not fix this issue,Please come to LiveSupport at
