[SVN] Switch to a former version forever

Hi there,
This is the first time i ask a question here so i hope i will give enough
information.

OK i have a SVN repository at the version 568 for my application
On my local machine, my application is at version 568 but i want to come
back entirely to version 562.
So i did this (using the SVN plugin for IntelliJ Idea, which is my IDE), by
updating to version 562.
It worked.
But then i wanted to commit everything, a way for me to tell the repository
"ok those changes are the latest, my come back is definitive"
But when i want to commit, SVN tells me that there is nothing to commit.

So i'm requiring your help to solve this.
And if you could help me and give me a general way to come back to a
previous version and put the repo in this previous version.

Nicolas.
