Is CrowdGen/Appen just a huge waste of time?

I just signed up and so far, it's been a very confusing and frustrating process. I was accepted to a project but when I click on the project it just takes me to a blank page. I tried to apply to another project and it says "you must add your primary language again as a secondary language on your profile", however the platform does not allow you to do this. I also started another project and after completing the test questions was told "there are no tasks for you to work on". So basically it's been a huge dead end and waste of time so far. Should I just give up?
