Minecraft Saving Chunks then Black Sreen Question?

I tried downloading the rigusamis Elemental Arrow mod for my account i tried to follow the tutorials on youtube exactly but they never ever EVER ******* WORK!!! i have spent a total of about 6 hours over the past week trying to get it to work. i tried redownloading the minecraft files, deleting the meta file, putting the files from the mod into the minecraft bin files. Yes i have modloader and yes i have 7 zip. now whenever i open my singleplayer it says in the top left across my screen in pink letters that there was a problem with zombe mod installer which is what i used for my flying mod and whenever i right click with my bow out, it freezes, says saving chunks, and then turns black and nothing happens. so i am forced to not be able to use my bow and arrows + the mod is still not working and i have pink letters all across my screen. Can anyone tell me how to completely reset all of the information on my minecraft account and its files, or just tell me how to fix the situation i am already in? why cant they just have a button that says "attach arrow mod to minecraft account", you click it, and its done? uuuuhhhhgg im frusturated and depressed.
