So, when .mq4 file is compiled and there are error, a log file is created. Fxdreema tries to compile it, then looks for such file and if it exists it tries to extract information from it. This particular error appears when no information can be extracted, it's just a general message that says that there is a problem. But the log file is deleted immediately, so it will not be easy to see what's inside. But if you export .mq4 file and try to compile it in MetaEditor, it will probably show the problem.
