I noticed that in that past there have been messages regarding the licensing server. I am currently trying to develop my bot further after having left it run overnight for testing purposes, and the client is now asking me to purchase more credits becuase I have used all of my free credits…
Failed to prepare the bot:
You have exhausted your free bot use time. Free use of bots is limited to 120 minutes.
Using a bot costs 16 credits per minute.
To continue using bots with this app, proceed at http://manage.botengine.org/credits
I was under the impression this bot was still free?
The bot is still kinda free. you can get credits for posting here or buy them for a ridiculous cheap price. keep in mind that this is not only a bot, its a bot framework so you can automate pretty much anything in eve and that demands quite some sophisticated brainpower.
A currency is the fairest method to generate income from the bot and encurage contributions to the community. you can do what you feel right to earn the money or the currency for the bots usage, some people even work for that money. the developer certanly did invest work to make this bot.
