Thank you for all your replies..sorry I would have replied earlier, but I can't find the "Subscribe to Topic" button.

Back to the initial subject, I bought my licenses last year. If I choose not to upgrade to 2012 now, could I upgrade to a much later version, for example in the year 2022, for the same price?

And in the meantime, how much longer can I continue to purchase and download the old version, building up my map of the UK? I'm worried I'll end up with bits of old OS and bits of later versions creating a broken map, because tiles from different versions don't seem to appear on the same, seamless map.

I've invested £200 so far and I already need a larger area - just want to make sure I'm buying the right product.

Thanks
