Problema con el funcionamiento de Easy Populate en Zen Cart

[rbczgz]

Datos de la instalación:

Zen Cart 1.3.8a
Easy Populate 1.2.5.7

Bien, con estos datos tengo instalada una tienda virtual con unos pocos productos cargados. El problema es que cuando intento descargar el archivo con Easy Populate me da los siguientes errores:

Código:

Si en lugar de utilizar la opción "Download Complete .csv file to edit" elijo la opción "Create Complete .csv file in temp dir", me crea el archivo en la carpeta temporal, pero sólo con los encabezados y me crea también un archivo log con el siguiente error:

Código:

He estado mirando y revisando por todos los sitios que se me ha ocurrido pero no encuentro solución ¿alguien me puede echar un cable?

Muchas gracias por adelantado.
