Fixed
Ynot kindly helped me with a tiny "dummy" 1MB .hds file to replace the missing snapshot-file inside the .HDD. And then I replaced the blank XML-file with the text below. 
I had two .hds-files inside my original .HDD package. One of them was not working/missing. This way I finally got my XP working again 
 
I updated to the latest release (#4560) hoping it would solve the problem - but it does not automatically fix the problem.
P.S. Edited for spelling and clarity.
