May I recommend that you learn to run it from the command line. It's not
at all hard.
I've done several IDE's, and aside from the need to learn them, and
their bugs, they have the additional disadvantage of keeping you from
seeing what you're really doing.
Amen (and even more so for beginners)
Seems you are running an old version here, I happen to have good news
