Excuse Emon... he can be a little rude like that. You can't import a bsp file into radient because bsp files are completely unreadable and need to be decompiled in order to have radient read them. I don't know of any decompilers on the web that I can tell you of but I do know that not many of the decompilers out there are very successful at decompiling a level without errors. I suggest you forget the idea and just remember not to lose those .map files! Once you lose that, you're screwed.
