I canceled the incremental package (136 MB), and re-downloaded all. And nothing, when applying the update i have always the error from the beginning. Now i try to manually edit the script. Edit: nothing, i cannot solve the problem :-( I also tried to remove all .doom3 directory, re-install all doom3 there from scratch, updated, and there run tdm_update.linux, but always with the same error when apply the incremental update downloaded. I think there is some problem on the script (the default path that the script try to use) Nobody has this problem with Linux? Edit2: I solved today: I deleted *all* doom3 stuff, created a new directory /.doom3/darkmod, copied the TDM_updater4linux there, and launched. It crashed/stopped 2-3 times on download. Re-Launched every time, it ended ok the installation, without any error! So now it works the main menu, and i'm completely without doom3 installation :-D I launched training mission and it works! (but with a lot of graphical bug, no trasparency on flames, gliches, black textures, etc etc) Anyway, i'm happy that at least now i can launch the main menu, first step done ;-)
