I have been using EarMaster in an attempt to train my ears. Has anyone got any advise on using the program or simply any comments about it?

I'm finding the going pretty tough on the "standard tutor" doing interval comparison. Its especially hard to differentiate with notes of very high and low pitches.
i`ve been using this program a lot,i think its great and very rewarding.
i`ve worked on interval comparison a lot,until i nailed all the lessons in it.
its important to do things in your pace,and not move on until you get 100% in the lesson.
being patient is the key here,your musical ear will improve drastically from this experience.
Thats good to hear Thats probably the problem.... I move on when I'm at like 90% so thats probably why the harder exercises are getting tough.
