A) List your system specifications please: it doesn't' always help, but sometimes it will show something obvious.
B) Are you positive ALL of the log files are blank? If so, try navigating to the actual game folder [Renegade X\Binaries\Win32], start a command prompt here ( if you shift + right-click there should be an option to "open command window here" ), then type "UDK -log". It should run and it should inevitably log everything from start to finish. If it doesn't get anything logged then that's pretty extreme.
C) What resolution are you using for your monitor?
D) If you could explain: why did you update to 5.002 in the launcher, then manually update to 5003 ???
