ssl install problem

Hi to everyone i hope you can help me with my problem.

i am trying to install ssl to my cs cart eshop via cpanel only, because i have no access to WHM.

i did all the steps in the ssl/tls manager and now i am at the step tha i have to upload the www.xxxx.gr.crt file and the gd_bundle.crt that godaddy email me.

but there is no ''Setup a SSL certificate to work with your site'' button in the ssl/tls manager.

my host told me to send him the crt files so that he will see what he can do.

is it right to give the crt files?

can he enable this button for me?

is there a way to install it without sending him the crt files?

i dont know if i must trust him.
