I was forced to download the new patch last night and like usual with blizzard and wc3 patches it totally screwed up everything. It took me a bit to figure out what the hell was going on but I got it to work smoothly again, i just have to have a few extra steps in the process now.
Lucky for me I save a backup copy of the default worldedit.exe
Basically for me anyways what i have to do now is switch over the WorldEdit.exe for the actual one I use when I make the map and then when I want to play wc3 I have to then change the names around and put in the default worldedit.exe so that wc3 does not blow up. In any event I have the new patched version and the old version for Newgen. NewGen apparently even though its separate file completely calls for check sums to the original world edit in the wc3 folder which causes the NewGen to blow up now every time you open it after you download and update into wc3 patch 1.23
If Sin, Pyth, or Zync are having these issues and have been unable to find the appropriate files to continue what your doing then let me know on msn and Ill send you the files needed.
