Wordpress - Fix My Plugin Problem

I use a CSV Import Plugin to mass-post real estate listings from a data feed (csv file). The plugin imports the data fine - categories, tags, everything looks good - except ... 1) The Previous/Next Post links don't display at all on the single posts. 2) Cform contact forms don't display in single posts. If I manually post a test post then the cforms display normally and the Previous/Next links appear as they should (in the test post), but the Previous/Next doesn't see the csv plugin-generated posts - only manually entered posts. I installed a fresh wordpress installation on a new database (no theme, no other plugins & no customizations) and had the same problem - so I am certain that it is the CSV Import Plugin causing the problem. I am uploading all of the plugin files so everyone can look them over before bidding. Terms: Upon completion, the repaired plugin must allow the Previous/Next post links to display normally in a single post on a new wordpress installation, the standard cform form must display correctly in the sidebar & there must not be any new problems. Thank you for looking. :)
