TO ALL WHO EXPERIENCE A CODWAW CRASH WHEN TRYING TO BOOT UGX CHRISTMAS:
There is a special new update in the UGX Map Manager for you to try. This update is currently UNTESTED but will hopefully solve the problem. To get the update, first update your UGX Christmas installation to the latest version (1.4). Next, install UGX Christmas (CRASH VER.). The crash will hopefully be fixed.
If your CoDWaW does not crash when booting UGX Christmas, DO NOT DOWNLOAD THIS SEPARATE UPDATE.
