Player wont use DivX codec

[camdish]

I have been using the latest player for a while now and it has always used the DivX codec (official one) when playing .AVI files. All of a sudden, without any changes that I am aware of making, it has stopped using it i.e no DivX logo, no controls for picture. While the file still plays, I want to use the DivX codec for the control it gives me over the picture settings. I installed ffDshow and configured it for DivX5 and BSPlayer picked it up and used it for playback. Deleted ffDshow and re-installed DivX but BSPlayer is still not using it. I have checked the player config. and everything seems to be in order so any ideas as to how I can force the player to use the DivX codec for playback?

Thanks.
