HaloMods "Classic" Read-only Archive

Im currently trying to run SparkEdit on the Virtual PC, Parellels. Everything works fine until i go open cache file. I select my Bloodgulch.map file which is in the Halo Trial folder and go Open, but it just says "Compiling Tag Relationships..." and it wont do anything else!
Am i soppose to wait an hour for it to load or something?

Please Help!

Wow lol i hade the same problem once but to make it work for halo trial download Sparkify and that makes bloodgulch (trial map) in sparkedit or you cand download HMC and you can use it to convert it to PC and then when you finish with it you convert it back to trial

just convert the header with a hex editor there are tuts on it
