Update of Affiliates Failed

Hi folks,

I saw the notification that I had an update, and I went to do it. The only update was Affiliates, and when I tried to update it, I got the following error message:

An error occurred while updating Affiliate: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

Could you please fix it please?
Thanks!
