That's a bit better. 1.1 changed rather a lot on the screenpack front and they are known not to work that well between versions.
If you want to use it, open the default screenpack system.def alongside your custom system.def. Scroll down line by line. If a parameter is missing, to take an example, localcoord, add it with the same values as in the system.def.
If you have something like notepad++ and the compare tool you can look at all the bits that are different, it'll highlight all the numbers, but more importantly should highlight the differing lines as well.
SFF should function fine. Fight.def and system.def not so much.
