from http://www.techyv.com/questions/error-message-winff-software that there seems to be a simple answer.
Close the program down then navigate to C:\users\LLL\AppData\Roaming\winff\ using Windows Explorer and delete that cfg.xm file
Try the program again.
I have no information whether that works or not.
I have been using the Winfx Video converter for a couple of years without any problems. I had to reinstall it due to a full system recovery and now when I try and open the program I get the following error message:
"c:\users\LLL\AppData\Roaming\winff\cfg.xm(1,1) Error: Expected element. "
"Press OK to ignore and risk data corruption."
"Press Cancel to kill the program. "
Selecting "OK" opens the program, but the drop-down menus for Output Details are not functional. Adding a file and selecting "convert" causes the same error message to appear.
Selecting "cancel" closes the program.
I've tried uninstalling and reinstalling the program a couple of times with the same results.
