Depends. Which version is the map supposed to be for? If it's supposed to be for 2.2, you can
download the 2.2 configuration here. Personally, I've had problems loading SRB2 in ZB, and the easiest workaround for it that I have is to just save the map manually and add it in SRB2. You can load 2.1 in ZB just fine, however, but that's not 2.2.
