Add-On Not Uploadable

[idyllicforums]

I've never edited an add-on and I've run into trouble.

I need to edit the code for one of the adons I'm trying to install to make it compatible. I have to uncompress the adon in order to edit the code, but when recompressing the add-on will fail to load into Xenforo through the admin panel. I hope I'm not missing something obvious in the documentation, but I can't seem to find anything. I appreciate any sort of help, thanks!
