I can't submit publication in Labjam

I filled all the fields and I attached the pdf file of the publication. But I get the error message: "The filetype you are attempting to upload is not allowed". The pdf file seems to be ok. I had similar problems in the past so it seems this problem hasn't been fixed yet. I would appreciate your support as soon as possible due to time constraints with the submission date. Thanks
