Deleting present file on RootsMagic and reinstalling it from Ancestry.com, can this be done?

New to RootsMagic and pretty sure I have messed up over the last week adding changes from Ancestry.com. Would like to delete the file & start again, is this possible?

You can start a new RM database and connect it to Ancestry with TreeShare and download your Ancestry Tree to it. That does not require the deletion of the current database file so you can delete it whenever you want.

Thank you, thought about doing that but was nervous I would add problems. (not always the brightest button in the tin), bit out of my comfort zone
