I just updated my core on the site from 7.15 to 7.18

I have three modules that I am trying to update.  When I try to update I get the corresponding error message:

Colorbox:     

Downloading updates failed:
•Invalid checksum for file "; $Id$ core = 7.x api = 2 libraries[colorbox][download][type] = "get" libraries[colorbox][download" : 22940 calculated, 0 expected

Entity API:

Downloading updates failed:
•Invalid checksum for file "name = Entity API description = Enables modules to work with any entity type and to provide entities" : 47162 calculated, 0 expected

Ubercart:

Downloading updates failed:
•Invalid checksum for file "name = Tax report description = Provides a report of sales tax your customers paid. dependencies[] =" : 27537 calculated, 0 expected

What should I do to fix this?
Thanks
