I am currently browsing through your donation options, because I am interested in donating. However when I try to get past the shop home screen it asks me to put in my minecraft account username(FreedomEagle21). But when I enter my IGN it says it is not a legit minecraft account. I know for sure that I have premium, and I am wondering how I can get past this error. Thanks for helping
This happened to me today for the first time in weeks. I did vote1, as usual, and it said I needed to wait tomorrow before voting again. I then went to trying to vote from the 3G connection on my phone (so it wasn't the same ip as my wi-fi) and the same message came up. I never got the nether star in game. This is a bit scary to me, since I'm going for a vote medal/coupon again in January... if the votes aren't registering, I'm much less likely to get the coupon, which kinda scares me.
I am having this same issue. I go in and put in my IGN, which matches my Forum name, and it tells me that it is not a valid minecraft account.
Update: So i ended up logging into my Minecraft account at minecraft.com and had to verify my login. Once I did that, tried the ECC shop and it accepted my IGN
This was a buycraft issue that they had been working on fixing. It should be fixed now. https://twitter.com/Buycraft/status/550662353180950529
