is it possible to install another version of Ubuntu in my newest version 11.10? Something doesn't work well in this new version; see my post. I may need to switch back. Thanks a lot!

I don't know about install "in" unless you use a virtual machine. You can install "over" by getting a 11.04 CD and installing like you did 11.10.
