I've installed the Dude version 4.0beta3 on the server production (windows server 2003 ) and i need to do something offline, I try to export data from The dude server, create a new one on windows 7 and import data to it.The problem after I try to import data to new dude show you below.

Error: Connection failed : No connection could be made because the target machine actively confused it

Has anyone known the problem and how to fix it?
