slodka I'm very sorry, but not really 🙁 In theory seems there wouldn't be a problem to perform such an upgrade, however, from the legal point of view, it can't be done at this point in time in your case. It could be done differently, if you would buy, wouldn't activate the license, and you would fit the period mentioned in terms (see VI. C.). Then, at your request, I could do a refund for the single and you could buy the indie one. So it would be in line with the terms and invoicing would be appropriate. At the same, I want to remind you that the intro sale prices last until the end of September. The normal price will apply from the beginning of October. So you have still few days to grab one more at a lower price 🤗
