I've used LoadFromFile to export my SoftType & the result is 3 files, SoftType_0.xml, SoftType_1.xml, & SoftType_2.xml.
I then copy those files to my production server, and again, use LoadFromFile to import.
The files SoftType_0.xml & SoftType_1.xml are imported properly without any errors.
The file SoftType_2.xml hangs for hours without completing.
I've made sure the global attributes used in this soft type already exist.
We're using 10.2
