I'm having an issue with TezBox. I have my ICO wallet there, with the XTZ I bought at this time, and I activated it but never did anything with it. Now I would like to start delegating but for that I have to create a KT1 account. And when I try to do that in TezBox, it says "There was an error adding account. Please ensure your main account has funds available.". Of course there are enough funds, I have more than 1000 XTZ in my account. Any idea what I am missing?
