Blockchain wallet is fine. I read a bit on your behalf as I have never dealt with a blockchain wallet. The method for retrieving the private key seems kind of complicated at this point, at least from what I read. There is plenty of time though and rather then go through a series of explanations that might just confuse you, I recommend contacting their support team and having them walk you through it...
Thank you very much! You're very kind for looking into that...I did too but thought it would be something less complicated so the best is probably to contact support as you suggest. I will stay around here in any case to read about the developments and news! So excited!!
