When IRADs WebSphere Test Server Fails to Respond

My test server keeps failing to response; when I right-click on it in the servers tab, I can't even get a context menu. Well, I just want to stop and restart it, so to stop it, I just went right to the bin directory and issued the stopServer command. Even though it's the test server for rational application developer 7.5, the stopServer and startServer commands in the bin directory still work fine.

Here's the command:

C:\_irad\core\runtimes\base_v7\bin>stopServer -server1
