I ran into two initial problems when trying out TDM. I have a fix for one that I'll share in case anyone else encounters the same issue. TDM Update CrashesRunning tdm_update.exe results in a crash: 'tdm_update.exe has encountered a problem and needs to close.' This happens shortly after the copyright line of text is displayed. A zero length tdm_mirrors.txt file is created. If I manually obtain a correct tdm_mirrors.txt file and run with tdm_update.exe --keep-mirrors, the same crash happens just after 'Fetching checksums from server...'. To workaround this problem, I used the torrent to get the game. Following the wiki suggestion of cleaning out %temp% did not solve this problem. Second start of game = Black screen with sound, invisible menus, and generic grey mouse cursorThe new 'DoomConfig.cfg' created after the first run of the game had a setting that would cause this error. Through trial and error I determined the setting I needed to update: Change seta image_usePrecompressedTextures "0" to: seta image_usePrecompressedTextures "1"
