Ultrastar randonmly freezes

[ingridguerci94]

I'm trying to test a few songs with ultrastar deluxe and liked it, now after downloading a few packages of songs, the game randomly freezes while trying to select one or just after selecting a category of the main four.
I'm trying to prepare it for a party and the thing just freezes leading me to do a forced shutdown, it started to happen after I added 30 songs and the list rises to 97.


I have a Lenovo Idepad Y530 and plenty hard drive space, so I don't know the real cause of the freezings.
