MUSYNX strange problem

I don't know how popular is Musynx, a DJmax-like. The game is not so bad, it misses many little things but it's still fair. BTY I have a big problem, I can't play several tracks in 4K easy and hard and more in 6K.

I uninstall the game and DL it again but nothing changes.

Here is a list of the unplayable tracks :

Little red ridding hood's daily
Journey
Next for place
KOI
Kerberos
Legendary
Cord player
Shattered skies
Annihilator
Su-San
Century of god
Find me

 

OK guys, it works now. I just change the language of my PS4, it was in french. The fact of changing it into US english resolved my trouble >｡< no more freeze at the beginning of those 12 songs.

I tried the game on a PS4, a pro and a PSvita, if your language is not english, you'll have the same problem, so to play all the tracks you have to change your console language.

 

Today we had a big update that brings 41 new tracks and erase all your hiscores. Take care if you're doing trophies.
