Just uploaded the two files to use the MT Plugin called SubCategories

When I try to go to the mt-sc.cgi file in my movable type root, I get the following error:

An error occurred:

Can’t locate Storable.pm in @INC (@INC contains: c:\myhost\myaccount\movtyp\extlib
where C:\myhost is the root dir and myaccount is myuser subdirectory

Any ideas? I will link to the trackback for David Rayner’s site here
