Reinstalling won\'t help because you\'ll have to update to be able to connect on the server and once you\'ve updated you\'ll have the latest version of the updater and such which is the one you currently have, so it\'ll start crashing all over again. (I believe.)
Instead, you should probably just try executing updater.exe --auto to update until it\'s fixed.
That is, right click on the Updater shortcut in start menu, select properties, and append \' --auto\' to the target box, while preserving the original contents. (Note the space before --auto.)
The updater should now work.
(Oh, and the normal updater crashes me. Only the --auto one will work.)
