help - cannot upload pdf file to site

Thanks, morgan, but I don't even get the option to "put" the document.  When I right click on the pdf file in the local folder, all I get is "new file, new folder, open, open with, edit, select all, preview in browser", or "copy, paste, delete, rename".  I have tried copying and pasting to the server, it did not work.  I have tested my links in the html page, and they are correct.  I used to be able to either "put" or "save file to remote server" to place documents, but now I don't get those options.  The document is there on my local folder, it previews in the browsers correctly.  When I am in the remote site, browser preview gives me the "file not found" message.  When I try to open the document from the remote site, I get the message "Adobe could not open the document because it is either an unsupported format or was damaged".  I have deleted the document, created it again, saved it in the local site again, but cannot seem to correct it on the server. Like I said, I am not very knowledgeable in this stuff, so maybe it's something incredibly simple that I'm overlooking?
