Have installed AC 13 on a windows XP. Wibu version 5.20 with a WkLAN server set. When I start AC 13 it can not find any licence. If I start AC 12 it works fine. If I am on a LAN and remove the server from WkLAN server list I can start AC 13. Is there anyone else who have this problem and can give me some suggestions on what to do?
