What update? You only need to reinstall the program if you deleted it. In Windows to update go up to Online - Check for Updates.
We are not sure if you actually used the CD Desktop program or you accidentally used the online version. Do you see a black column on the left side saying Federal, State, File, etc. or a blue menu across the top.
How are you trying to start a new return? The Desktop program can do unlimited returns. You need to save each return with a different name.
When you see your return then go up to the top black line and the first item on the left, click on File then New Tax Return.
