HaloMods "Classic" Read-only Archive

I edited bloodgulch in HCE so that the hog has driveby and shoots rockets that do low damage but have high force. I also disabled all other weapons by setting them all to warthog gun. Also replaced all vehicles with warthogs.

Now the problem I have is I need to make the rate of fire much, much slower. Right now it fires rockets rapid fire and thats no good. I was told to open the map in HMT and go to the weapons foldout then set the rate of fire there but when I enter a number it gives me the error "Error while writing to file structure."
What does this mean and how can I fix it?

it does that if you try to type .75 or .5, you must put 0.75 or 0.5

Error while trying to update and write structure.

It does this no matter what number I enter, and it does it on the first keypress.

hmm i get the same problem, all i do is press a number and it givs me the eroor
