Note: Text::CSV and Text::CSV_XS are different modules by different authors. Sure you installed the correct one?

Also, a few XS modules wont correctly work when instaklled with PPM. Try this on the command line:

perl -MCPAN -e shell
install Text::CSV_XS
[download]

Answer all the install (temporary) this or that questions with yes. Post any errors you encounter.
