Corrupted pdf after upload? Help Needed

Here is my problem

I have uploaded a pdf file of 2.3MB and post it on my site. When you download the file Adobe Reader gives the message the file can't be opened because the document type is not supported or the file has been damaged. A smaller pdf works fine (rfid paper is placed on same website).

- dashboard file information is correct (file size and type)
- constraints in php ini for post and upload are both 50M
- original file can be openend in pdfreader
- uploaded file multiple times but all with same result

location of the file on website that can be opened:

page where the download file link ("Kiva") is placed that gives a corrupted pdf:

If any one knows the solution for this problem
please help me :)
