When I open the reader, I just started getting the error "The ordinal 4369 could not be located in the dynamic link library libeay32.dll", and when I close the error, it crashes. After that, it opens fine. The oddest part is that it only happens once a day. If I restart the same day, I don't get the error.

I've already tried un/re-installing, and removing the C:\Users\your_username\AppData\Local\YACReader file.

hmmm, YACReader shouldn't be using that .dll

Try downloading it and placing it in the YACReader's folder, just in case Try with this link www.dropbox.com/s/sq47j673hpk47rt/libeay32.dll?dl=0

I put one in there. I'll see what happens tomorrow.

In a side note, it started happening right after I uninstalled a bunch of old programs.

Seemed to fix it on opening today. Not sure how that library got linked. If it's still fine after the weekend, that should be it.
