"Unrecoverable Error" when trying to open or import DXF Files

Hello,

I am trying to open some DXF files in CorelDraw X8, and when I try to open one I get a message that says "Unrecoverable Error". This sprung up out of the blue, and I don't think it's based on the particular files, because files I have already opened in CorelDraw no longer do. I have tried rebooting, using different computers, and opening while holding down F8 (I think this is reset?) but nothing has worked. Any help would be greatly appreciated.
