Hi, Ollsky,
You should find that these are not errors in the code, but warnings, this has happened because Spotware has upgraded the cTrader API, but all historical indicators and cBots are still compatible.
The cBot will still build and run fine as these are just information messages letting you know there are updated methods etc to use, you should be able to easily update the code if you wish by posting on our cTrader code forum or the cTrader official support site with single examples of methods or properties you are unable to update.
