How do I restart or reinstall notes?

I found the following on another discussion. It includes macjack's suggestion, as well as clearing cache. I think the suggestion number 3 below is not quite correct, and macjack's suggestion should be taken instead:

Now we are going to fix the duplicating notes issue. I found this solution on another thread(https://discussions.apple.com/thread/4137558?start=0&tstart=0). This person actually called Apple and was told to follow these steps:

1. Click on mac HD/ library /caches. drag all the contents in the folder to the trash
2. Click on the finder click go, hold the option key and click on libraries (will not appear if you don't hold the option key). go to the caches folder again and again drag everything in the folder to the trash.
3. Click on the finder click go, hold the option key and click on containers. Drag com.apple.notes to the trash
4. Restart your computer.
5. Empty trash.
6. Try to open notes again.

Update: I tried the recommended procedure above myself (to reiterate, number 3 was replaced with macjack's recommendation) and it fixed a problem I've had for several weeks with Notes; namely, my iCloud account was duplicated. It wasn't a crippling problem, just a bit ugly. Anyway, the cleanup fixed it and my Notes works flawlessly now.

So, thank you macjack, and Gavstar, I can vouch for the worthiness of the process.

Go to your Finder "Go" menu hold the option key to choose "Library". Then go to Containers folder and find and delete com.apple.Notes/Container.plist

"Click on the finder click go, hold the option key and click on containers. Drag com.apple.notes to the trash"

I have Mac OSX...when I do this proceedure there are no "Containers" to select. Is that on an older OS? Where would it be in OSX Lion?

Try deleting the other iCloud account, not the one you tried the first time.

Check the update in my most recent post above. That will answer your question.

sberman's solution solved a problem with Notes for me, I had one note that could not be deleted, whenever I tried to delete it, the program would crash.

I had main electric shut down.

when restarting, notes had disappeared and could not sync.

Tried this method and worked immediately.

I really dont understand what is being said in the first step, and I'd like to fix my notes...can someone please explain whats being said in layman terms?
