I have 2  problems regarding render which have occurred today after long time trouble free use.

Windows 10 LRT 4.7.3 and today I couldn't select any file to render from the dropdown menu in the path box. the path box froze as did LRT. Reboot required. Several attempts and same result.
So I updated to 4.7.4 and updated the latest java.
Same result.
If I perform a workflow and export from LR and try rendering that new
file I get " external encoder returned an error please check logfiles". One thing I notice [see attached log file] is 'value 9 for parameter color primaries out of range [1-8]'. If thats one of the problems where do I find it to alter the value?

I'd sure appreciate your thoughts.

For Problem 1: try deleting C:\Users\YOURUSERNAME\AppData\Roaming\LRTimelapse\user.props
This is in a system folder, so just paste C:\Users\YOURUSERNAME\AppData\Roaming\LRTimelapse in your location bar in the explorer, hit enter and delete the file. Make sure that LRTimelapse is closed before.

For Problem 2: see faq: http://forum.lrtimelapse.com/Thread-rend...to-value-9

Success! 
Thanks heaps.
