HaloMods "Classic" Read-only Archive

Hi guys,
when i use HMT i can only change checkboxes because when i try to change a value it says "error while trying to update and write structure" and if i ignore it, when i open the map again the value returns to its original value. I have downloaded like 5 .net frameworks and it still doesnt work. Can some1 help me out???

are you making changes like ".5" when they should be "0.5" instead? if your on vista are you running hmt in admin mode?

I got this error when I started using HMT. Do what Pepsi said and give an example of a value you are trying to change.
