Well, try to backup your ISO somewhere, and don't mount it on any drive. Open your WE, and you might also want to tell us what was your map and what was in it. You might have something wrong with your map instead, have you tried saving with other maps?
If you didn't use the regular cds when you installed warcraft, that's probably the problem. The only option I know of is to go and re-purchase the game again. Even if you bought the game before, we don't support pirated versions of the game or cd-cracks here. I don't know much about them myself, but from what I've seen world editor doesn't work with those programs.
I reinstalled recently using my friend's WC3 CD's... legit... The ISO isn't mounted and is backed up on a removable hard drive that is not connected to my computer. And any map (Even if I just hit new map then try to save) crashes WE.
On a side note when it is saving the part where the status bar (indicating what it is saving at the moment) gets to is Generating Map Script and below it states that it's working on the Header.
Either or, I'm currently in contacts with a Blizzard support staff via Email... he's been nice and tried to help, but so far no luck... He tried to get me to remove Daemon Tools, did so, didn't help at all. I'm getting tired of all this and just want it fixed. If you think I'd have more look in the General Tech Support Forums then moving it there would be great.
looking at all the posts i say suming is interfearing with your Warcraft3 III. I had those exact errors for 2 days sraight drove me flipping mad untill i uninstalled some sercruity software that was out of date. I dunno if its the same with u but it looks like you have sum kinda tool messing it
if you bother to re-install WC3, try manually deleting EVERYTHING that remains in the Warcraft folder in Program Files after uninstalling. maybe there is something that was left unnoticed in the folder thats causing problems, there can be some really nasty stuff (i had a map before which forced me to reformat my PC because of svchost errors everytime i started the PC)
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
