Problems with LR 4.4.

Hi

I have recently had some problems with LR 4.4.

I tried to use the LREenfuse plugin without success and now have additional problems, first this plugin loads OK but fails so far through......

More of a concern to me is that now when I close LR and restart, the plugin has gone, I have also, setup a 'auto import folder' which works fine until I close LR and restart again, the watched folder needs to be again specified, this entails removing the images and start from scratch? again lost when closed, yes I've clicked the OK button.

Lightroom itself also starts at the restore down size and whatever i do it now always starts at the reduced time which i think is linked as i had no problems before.

Any help would be very welcome before i have to reformat my Windows 7 laptop.

Fixed, a lot of files in my C drive were hidden? including all my music.
