Version 5.2 does NOT correctly create zipped files (at least if they have network links in them) and there is no record of this bug on the users forum yet. The last time it took nearly 9 months to fix, so don't hold your breath.
If you have already "updated" to the 5.2 version you can easily roll back to the version 5.1 at: Google Earth Advanced Download. You will need to un-install 5.2 before you do this.
In addition I have now restored the correct Nevada and Arizona USGS waypoint files.
