are you saving everything when you leave? after you add somethuing you have to save what you edit and save the info to a dll file. also the script file might be causing a problem. just move some where and do your work over.
And when you brought up the mod from flexplorer, did you see all the new discovery systems? Or was it vanilla (ran into that problem myself.. 
well theres a problem with xml script with fl explorer you have to move those files then replace them when you are finished and i bet you it will work.
There's a tutorial by Dark Dragon for Freelancer Explorer.
It's in three parts so you'll have to find and download all three.
I know it's in the downloads somewhere, I've seen it, but you'll have to search.
I don't remember if I saw it in the Tools, Tutorials or Unsorted section but I know it's there because I put it in the downloads myself, a long time ago in a galaxy far, far away 
You will also find them at FileFront, seach Freelancer, then they are in the tutorial sub-directory.
Hope you don't mind me editing your post Tunicle, wanted to give links to those tutorials you mentioned on FileFront.

Hi all,
Is there any FlEx where i can set the exclusion zone after marking?
aaaand, just in case this still isnt working. I had the exact same problem... I think it was just my downloaded version of fl explorer. I downloaded a different version (which was also the newest) and it worked fine. Try getting a different one.

Ive solved this problem, you have to do it manually in .ini files. If you are interested how to do it i could tell you.
