You don't need to extract the campaign file from my Fritz 5 Maps.zip. Just rename the zip extension to pk3 and put it in your fritzbot folder. Crapshoot has made a template for creating pk3 files. A link to it is in the ET Wiki under the heading "Installation of Addtional Files." That's what I use together with WinRAR.
I don't think that anything is wrong with your WinRAR. Perhaps you forgot to put the campaign file into a "scripts" folder in your zip/pk3?
I added some more campaigns to my system and found that I got the same problem that you have described. It seems to me that there must be a limit in ET for how many campaigns that can be loaded at a time. That's why I suggested dumping all unnecessary campaigns and just keeping the ones you want at the moment. It seems to hit the limit and then takes the data from the campaigns near the top of the list. If you put Fritz 5 Maps at the top, it will be the one loaded in place of the ones on the bottom. I don't know of any other way to fix this little glitch.
