DMS 1.11 is the last legal version, all releases after that were just unlicensed hacks from scene groups (that's why they're not on Aminet). Many DMS versions throw Enforcer hits and, as you noticed, sometimes a DMS archive can only be extracted with the exact same DMS version that was used to create it. DMS' error handling is generally a nightmare, anyway.
Stay clear of DMS, ADF is the much better and safer alternative. And you can mount ADF images without having to write them to a disk.
I didn't know 1.11 was the last from the original author. I found some docs (but not the executable) for v1.53 and it had this say:
"PRODIGY found a bug *MADE IN V1.11*, which I didnt really think
about when I made DMS to work with fastfile system disks..
and this is true that the OLD dms v1.11 cannot unpack those
disks, and therefor I have changed "NEEDED VERSION"
to be v1.51 for unpacking FFS disks.
Maybe Gulliver, like me, uses FFS to recycle floppies.
I've never tried ADF. Time for something new.
