You may wait on re-install of PD if things seem to be going fine, but you should be familiar with the re-install process because you will eventually need to do it for some reason.
You should not lose any projects when you do it.
Remember to ignore any commands to re-install Smartsound Quicktracks during the un-install of PD or you may lose any music files you purchased.
Back up Smartsound if you buy music from them.
If you are experiencing choppy playback, try lowering the resolution of your preview window. It is the icon under the preview window, third from the right.
