You stop paying rent, you can't live in the apartment any more... oh, and your programs also stop working
You may go back to CS5 but do be aware that your project files are not backward compatible
If you (for example) used PProCC to start a movie project, the project file will not open in PPro5
Thanks! So if I uninstal my CS5 version can I reinstal it later? On the same computer with the same codes?
Deactivate CS5 first (Help > Deactivate) then uninstall.
