+ 0 Votes Is it ALL pdf's, or just the same one? jdclyde 5 years ago Many pdf's are huge (because people don't know how to correctly make them). Try to download the pdf, and then open it locally. another thing to try, clear out your temp folder and cache. Close ALL applications, go to the run and type %temp% select all, and delete. reboot. Then try to download the file and open it.
