Installed the latest version of jmeter apache-jmeter-2.13 Jmeter plugins JRE JAVA8.

    Judging by the text CannotResolveClassException and kg.apc.jmeter.samplers.DummySampler - there is not enough DummySampler plugin in the lib/ext folder.

    DummySampler plugin is in the standard set of plug-ins. Visit http://jmeter-plugins.org/ , download the Standard Set and install according to the instruction http://jmeter-plugins.org/wiki/PluginInstall/ :

    1. Unpack the contents of the archive into the folder with JMeter (new files will appear in lib / ext).
    2. Edit the configuration file {%jmeter_bin%}/jmeter.properties uncommenting the line jmeter.save.saveservice.thread_counts=true .
    3. Create or add to the configuration file {%jmeter_bin%}/user.properties lines, as stated in the instructions.
    4. Restart JMeter.

    I guess that will help.

    It happens that the RAM is not enough to start.

    There are no other reasons why the jmx file does not open.
