MTSimpleComments error

I just installed the latest version (1.32) of the MTSimpleComments plugin, but receive the following error when scheduled posts are being built:

Undefined subroutine MTPlugins::simplecomments::SimpleCommentCount at lib/MT/ line 139

The strange thing is that all files, both from index templates as archive templates, are created correctly, except for the main index.
