Winff missing root element

Ubuntu 18.04

So, everything was working fine till today. I was converting files from mp4 to DNxHD for use in DaVinci resolve. My machine started acting up and the conversions slowed way down, so I rebooted and when it came back up my winff gives me this error:

In 'file:///home/cody/.winff/cfg.xml' (line 1 pos 1): Root element is missing.

Press OK to ignore and risk data corruption.
Press Abort to kill the program.

I can't find anything specific on that issue. The cfg.xml file is in the folder but it is just a blank file. I tried uninstalling it through synaptic and reinstalling it with no change. I tried apt-get purge also with reinstall and again no change. What goes in the cfg file? Or how do I fix this?

thanks
