Weird problem i am having, i am using phptopdf to generate "invoices" in a site and all is working well but the files wont open in acrobat reader and acrobat reader alone, i even tried old versions of acrobat reader (11) since i heard the newest version has lots of bugs, tested it in opera,firefox,chrome,foxit reader and it all works fine.

i am asking here since the contact form for the site is unusable since reCAPTCHA one is defunct, anyway here is my phptopdf.php so you can take a look, but i think everything is in order
