Have you tried to update your dl links? chrome was blocking my old links but I updated them now it's back to normal.
It won't because now you will get a download link from another domain than the domain which is now blocked by chrome. I have made it a habit to regularly try initiating a download of one of my files to see whether or not chrome is blocking the file.So if you recreate your links chrome wont pop up telling its untrusted and potential virus type of website?
