Hi Jen,  Just for some info for you and anyone else reading this, there is sometimes a way around a corrupt zip.  If you right click on the zip and hit "explore", you can then copy the runtime folder to somewhere else on your HD then rezip it.  Sometime you have to open the runtime folder and copy each individual folder and sometimes you have to open everything and copy one file at a time.  This works for me about half the time I try it, but I ususally make this attempt before I lodge a problem.
