Please try updating to 5.12:
On what OS is the problem happening with you?
Exporting a configuration to another computer cannot be done easily. Of course the OS needs to be the same and programs need to be installed in the same place.
However there is more to it. All rules as they are stored in the registry or exported to a cfgx file will have a User ID (UID) string that you will have to edit before importing a configuration in another computer.
