Account deletion and re-setup assistance

Morning Support, Over the last few weeks of getting my head around the application, I have made numerous errors (learning mistakes) and have "resetnow" the account so I can start from fresh. This has worked well but the "shareholders" were not deleted. I tried to find out where to delete them but to no avail. I then added a new shareholder - this has now shown more shares in issue then actually exist. Can you please help me to delete all shareholder information or reset the account to completely blank so I can start again. Many Thanks :-)
