I just installed the VC++ thing and DarkRadiant, and when I load DarkRadiant and click OK on the DarkRadiant Preferences dialog, I simply get the error "DarkRadiant.exe has encountered a problem and needs to close." I checked the log file, and it gives the same error: ModuleRegistry: Warning! Module with name MainFrame requested but not found! Could it be a problem with a space in the folder name "Doom 3"? Surely Mamba26 and I aren't the only ones who have that, though...
