I have also experienced this when importing a standard Hansa import file, using System > Imports > Manual File Search. This would indicate it is not a HAL issue at all.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
