When you download the file that contains all the WAE source code and compiled cBots and indicators, unzip the folder called indicator files and double-click your mouse on each file to install. You can now test each indicator by attaching it to a chart. I tested using cTrader 4.6.6 and they load ok.
Looking at your log, it looks like there was an error loading the indicators, please install them first as described above and try again.
warning messages
Spotware continues to update the API and some methods become obsolete, this will show warnings on all cBots and indicators, but it will not affect the operation of the system. When they have finished the major updates of the API we will update the code and you will be able to download the update in your account downloads, in the meantime feel free to update the obsolete methods yourself.
The link below will also help you install the files.

first steps
I would first install the pre-compiled cBot and indicators and get them working, once you are happy you can start compiling your own modified cBot and indicators and post on the coding help forum if you need assistance.
modified code
If you have modified the code in any way in the cBot or indicator then you need to find out what is causing the problem or post for help on the coding forum.
