Issue extracting download with Smoothness theme

Issue extracting download with Smoothness theme


Hi,
I am currently experiencing an issue when I try to extract the zip
file I get when I download jQuery UI with the "Smoothness" theme.
When I download everything goes ok, but when comes the time to extract
the ZIP file, I get this error in WinRar :
! C:\pathToFile\jquery-ui-1.7.custom.zip: Unexpected end of archive
Same kind of error when extracting with WIndows built-in "Compressed
folder" :
The compressed (zipped) Folder is invalid or corrupted
Anyone has a workaround for this ? Or can a fix be applied to the
builder ?
Thank you
