This was made quite a while ago, there have been quite a few updates to civ since then, so there may have been some changes in the unit file format since then.
I might do an update, but I have a few projects I'm working on first, and if I do it'll be for beyond the sword. I haven't played BTS enough yet to really get a hold on the balance changes in it yet.
If you let me know what exact errors you're getting though I could probably whip up a quick fix if it's just a file format error.
The swordsman is the way it is just because there's not much point in giving it a melee bonus. It already clearly beats the spearman and loses to the axeman, which is as it should be in both cases. Giving it a melee bonus would just make it weaker vs axemen which is undesirable.
