Question about SDL Trados

Hi all,

I'm totally new to SDL Trados and I'm just starting to grasp the complexity of this extensive translation tool.

Working with SDL Trados Studio 2014, I'm trying to use the H&M filetype for translation of our H&M docs.
So I've imported that filetype in the new translation project in Trados.
However, Trados somehow refuses to import a H&M project (hmxp), saying that it isn't a translatable file.

Are there known issues with SDL Trados 2014 or am I doing something wrong?

Thank you.

Regards,
