Post Account Expiry - Existing Rise Courses

My Rise 360 account will expire shortly. The account contains a number of courses. 

As I am not in a position to renew my Rise subscription at the present time (and probably not for at least another year), could you please tell me what options I have in terms being able to get back to editing my Rise courses once I am in a position to renew my subscription.

I understand that any existing courses within my account will be retained on the Rise servers for six months after the account expires. However, in the case that I am not able renew the subscription within this timeframe, could you please let me know my options.

It would be a huge disappointment to find that my courses are somehow 'lost' after the six month server retainer period, as an immense amount of work has gone into authoring the courses. 

FYI - I have already exported/published my existing courses in web format.
