I thought I bought 150 HBC today on the ICO. Got the "you exceed the maximum" message as well, multiple times. I logged on my account 4 hrs after the ICO ended, and I still don't have the 150 HBC coins in my account. I had high hopes for this ICO. I have been trying since the first second of the first round of the ICO with no luck. Maybe I should turn on my VPN to Japan..might have some luck there..lol
