Another Error

Another error appearing [:D] Internal Error 2 in Module 48 which is 48-2 #Err_Zup_PutDataSize (Module_Zup,Err_Fatal(2)) for ZUP file. But still getting the same message only on one system. Config is as follows ver 2.01B Windows 2000 WinNT Server any suggestion ? And one more question I have got the list of all the error messages. But where can I get the solution for those errors.
