Yeah i have exactly the same issue here,one day all of sudden my FVD stopped loading the Preview thumbnails and was Loading endlessly,so i had to remove the extention and re-install it again,and now doesnt keep my adds saved and i must re-download them through the Server again and again!why this happened all of sudden?Plus i'm not using any cleaner for browser Data or any other cleaner.Any help would be appreciated thnx in advance!
