Hi, Gary,
When did you last download the tool, if it was more than a month ago I would download the latest version as many of our products stopped working when cTrader 4.2 was published, we have since updated all of our products to work?
If you have the latest version then can you provide the log information as a text file or screenshot?
Also, what is the version of cTrader FTMO and what version did you test with the original cTrader?
Can you also confirm that you are talking about the following tool?
