You might want to include the symbol files and models for the ICs. Before re-uploading a zip file, try putting it into a new folder, unzip it, run LTSpice, and make sure that everything that's needed has been included, i.e. it displays and runs OK.

It would also be a good idea to grab the LTSpice schematic screen image to the clipboard (Tools-->Copy Bitmap to Clipboard) and then paste it into Paint and then save it as a jpg or png and then post it here. Not everyone has LTSpice.
