I purchased TurboTax Incorporated for 2016/2017 and since I installed it my computer crashed. How do I download a new version without paying as I still have my code?

I have 2 businesses and one has a year end of Dec and the other is July. end.

I purchased the latest version (Nov 1/16 - Oct 31/17) and submitted my return for my company with the Dec year end. Since then my computer crashed and I do not have any version of TurboTax. I need to complete my return for my company with a July year end.

Do I just purchase a new version of Nov 1/16 - Oct 31/17 or do is there a way to reinstall this version and then purchase an additional return code?
