After patching to 1.7 I get this error at the end of patching and then the game won't start and this error message is repeated.

"The ordinal 5360 could not be located in the dynamic link library xlive.dll."

Only fix to restart the game is to re-install to release version.

thats games for windows live being its annoying self you either download the latest version of it or use this disabler http://www.fallout3nexus.com/downloads/file.php?id=1086
