I have lost the prospector zone

[Idsgt]

When entering the prospecter zone , worlds no longer appear, and the return to origin button does not do anything.  The collected artifacts are listed though.

Look for this file and attach it here:
c:\Users\YOUR_USER\AppData\Roaming\CreeperWorld3\log.txt

Can you describe where you last were, or anything about how much you have played the Prospector missions?  Also, are you playing the released version (1.04) or the latest beta version (1.07)?

I have 35,28,29 artifacts, maybe 10 systems into the prospector zone.  XP Pro computer, Released version 1.04

I do not have a log.txt file on the system except in open office

The only files in App Data are  Gamesettings,inputmanager, keydata

Use this on XP:
%appdata%\CreeperWorld3\log.txt

AppData\Roaming is only with windows vista and later.

The other thing you can do is to zip up you 'document and settings\CreeperWorld3' and mail that to support@knucklecracker.com (I read that email, not some imaginary support staff :) ).  If there is some issue with your persisted data that will let me see what the problem is.
