Will not allow me to upload PDF resumes.

Will not allow me to upload PDF resumes.

I am trying to import a resume into Zoho that is in PDF format but it doesnt allow me to upload, saying it is taking to long to carry on with my request. I have followed the instructions you have previously given me, to go into candidates, import document, but when i go to select resume format it gives me a list of countries rather than different formats. Is this correct? I would really appreciate some help as soon as possible as alot of our resumes are in this format and we need them online as soon as possible! Thanks
