syncronization prestashop with ebay

[electro altamira]

Hello

I am trying to download all the products from my prestashop store into my ebay store and i am getting this after the sichronization:

Mensaje de error de XML: "; nested exception is: org.xml.sax.SAXParseException: The element type "Description" must be terminated by the matching end-tag "".".
; nested exception is: org.xml.sax.SAXParseException: The element type "Description" must be terminated by the matching end-tag "".

also at the end of ebay module point 4 - store categories, appear this:

The following categories are not available for they contain subcategories. The eBay API doesn't permit sending products in these categories: Accesorios Portátiles, Accesorios Telefonía, Accesorios iPad, Accesorios Tablets, Accesorios iPhone-iPod, Smartphones, Conectividad, Imagen y Sonido, Software, TPV/POS, Periféricos, PCs/Integración, Portátiles/Tablets, Almacenamiento.

I download a few products, about 15, but i cant download any more.

Thank you
