cryptsy always has issues, most of the time it is their fault. Sometimes they do not show balances that you should have very fast, this makes your trade ammount in vaild and then the bot will stop working. If a bot is failing try changing the trade ammount first to see if that is the issue. The next step would be to try a new api, generate a new api key and see if that helps. If those two things dont help I am not sure what the problem could be , document it and create a support ticket.
