HaloMods "Classic" Read-only Archive

No i mean Spark Edit, I edit CE levels with it, but it wont let me compress it into a save file. As in not a custom level, normal levels I can't compress into a save file.

My Specs are:
2 GeForce 7800 GTs
2 gigs of memory(not shure what brand)
1 10 gig hard drive and 1 250 gig hard drive
AMD 4400+ Dual Core
Some sort of gigabyte hard drive.

With spark edit, I can edit normal levels, but not compress them into a save file.

So I just got my computer running, I installed halo, and halo CE, and HEK 3.5. I've got problems with almost all of it, Sapien starts to load the tutorial but then closes, I have 32 bit high color set too. When I click on tool it opens then closes, it says something but I don't know what, Spark Edit...
