Sorry, subtitles are not my turf, I am totally ignorant about subs. You will have to wait for MrC, but I suppose that he will be quite busy with real life at this time of the year.
What you should do in any case is post your log file (do not attach files in this forum, post the text directly or upload it to SendSpace or ZippyShare).
Whatever, after a crazy year 2015 I wish everyone a Merry Christmas and a Happy New Year...
Cheers
