I've had this problem on two prior mod versions. The only thing that ever worked was to redownload. Try deleting the mod before redownloading, downloading it into a different folder. Those are the only things I know of to get rid of the missing central directory messages.
dude i deleat it, and then redowload it and it DL really fast, like i never deleated it, and i have tryied everything but same problem
EDIT, i have also tried saveing it to different places, and it does the same thing, and still has the error. this is making me mad.
EDIT Again, I think ill just put my server up with 4.80 beta 2 untill this gets fixed. if u wanna stop trying and come chill, i got Np with it, as i am trying to start another community. but server is up and running.
The problem is that the zip file structure is damaged.
I've tried to rebuilt it, but with no success yet.
I couldn't recover all files on it because zip files does not contain any recovery info.
Well, the file on the server is 20mb in size while the file of the download link is 8.3mb in size.
