I recently redownloaded the app because I started to get more into rhythm games with my GF. If I don't link my old account, the game runs perfectly. However, the second I get all the time and effort I put in way back when reloaded, the game fails to open every time. I'm not restarting all over again especially when I had some high scoring titles and had actively used the monthly star package. If the game is ever fixed, I'll consider coming back, but for now, it's off to Project Sekai.
