You can use the old BB file to bypass the problem and then relaunch with the new one since the problem looks to be only on cold start.
1. Get a copy of previous BB.js in another folder
2. Rename it to oldBB.js
3. Move it to the gunbot folder
3. Launch "node oldBB BTC_XXX exchange" and wait to see the bot working correctly
4. Stop the bot
5. Launch "node BB BTC_XXX exchange"
