kdelibs disk image does not mount

Hi everyone,

I just have downloaded kdelibs disk image from the web site (webdav 
installation is really too long or maybe does not work ?) but it seems 
that the disk image does not mount (Error 95 : No file system 
available). Has anyone experienced this trouble ? Is there any solution 
but download this big file once again and hope it will work this time ? 
my connection is so slow that I hope it is possible to fix something or 
I have forgotten something to make it work.
