I was having trouble with several applications failing to update on the market so I just decided to wipe the data/cache, installed a new rom/kernel applied the market fix and reinstalled all of my apps. It went as expected except that google sky maps refuses to install with an "installation error" "unknown reason -18" in the market. I'm not sure how to debug this problem but I've looked through the phone and don't see any references to a stale sky maps files after wiping the data twice and reinstalling... Anyone have an apk for this I could try or any ideas what to do? I should point out that even my titanium backup of sky maps fails to install anymore. I have had no trouble recovering other programs' settings from the backups.
