When you build your level, do you get a dialog box with a few buttons and sliders, followed by a small window that displays the progress of the build? NeoK's problem (which I don't know how to fix, sorry ) seems to be that the dialog box doesn't appear after clicking "build." WED doesn't build "invisibly" -- the window should be obvious.

If this isn't the problem, here are a few other possibilites:

-Are there any errors listed in the small progress window during the build? Pay attention to these if they exist; they may stop the level from building.

-The errors say "Cannot find <EXTREME.WMB>" but the name of your level is WarriorsExtreme.wmb. Open your main script (WarriorsExtreme.WDL) using SED or a text editor like Notepad, scroll down to about line 20 and you should see a line like
Code:

---

string level_str = <WarriorsExtreme.WMB>;

---

If the name of the file is not the name of your level, change it to the name of your level (keep the .WMB). This might solve your problem.

Thanks for being so cooperative with details. Hope I've helped!
