I am fairly new to blender and I am having tons of trouble with a cloth simulation. I have subdivided cloth with the cloth physics modifier at stock settings and an object below it with the collision modifier but the cloth always falls through it. Here is the .blend file... help would be much appreciated, I'm getting so frustrated I kinda want to delete blender right now. Let me know if you need any more info, I am desperate to find a solution.
