If in the next few days the wallet problems aren`t fixed ( You had almost 1 week time ), you are doing more harm than good, you should think about giving back the early bird btc, recreate a new genesis block and launch again with a new wallet (this time don`t fork it from a coin code that you dont understand fully), and restart the early bird process again, with a new wallet forked from another coin if you are unable to resolve this problem just fork if from something that works and you understand.
With all of this, you took 6.5 btc, but the confidence and momentum is going away , so you need to get back the trust of the future investors, either by recreating everything and starting from scratch , or by solving the current wallet`s problems. And modify the topic, there is no succesfull Launch, 2nd stage didnt even start because you dont have a working network.
You launched something that doesn`t work. No worries, take the blame for it, recognize your mistake, because mistakes happen we are all human, give back the btc , recreate the wallet from another source coin and relaunch. This will show people that you have the balls, as a team to make decisions for the good of your investors, recognize your incompetence and take responsability , and take the actions needed for your coin to succede.
