UltraStar not working for me

Basically i tried to go on it today to sing one
of my favourite songs because i was bored, it
loaded up and everything suddenly it started
zooming in and out and left me on my desktop,
so i clicked on it again on the taskbar and it
zoomed in and out again, it happened many times
i tried to reinstall it and everything but it didnt work.

Anyone have an idea on how to fix it?
Thank you

there are different kind versions of ultrastar. Maybe you need another one.
What kind of Operation System do you use?

Oh my UltraStar did same to me and said error about graphics or something.
I don't know what I did but after those it started to work. I wish I could remember.

...maybe I just reinstalled too many times....

Hope you get it to work. :)
