Cant Update to membership2 from membership1

Hi, when I'm trying to Auto Update this is what it wrote to me:

Downloading update from https://premium.wpmudev.org/wdp-un.php?action=download&key=e6bd2f5848e56b04d8281b450a34287579bcec90&pid=1003656…

Unpacking the update…

The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

What to do please?
