Device not mounted error? BLJS10318 - Jojo's Bizarre Adventure Eyes of Heaven

Hi,

Tried to start up the game, but it black-screened with this error:

Code:

E {PPU[0x1000009] Thread (CRI FS File Access 2) [0x01da8c74]} sys_fs: sys_fs_open(“/dev_bdvd/PS3_GAME/USRDIR/data/system/nuccMaterial_ps3.nsh”) failed: device not mounted
E {PPU[0x1000009] Thread (CRI FS File Access 2) [0x01da8c74]} 'cellFsOpen' failed with 0x8001003a : CELL_ENOTMOUNTED

Is this the sort of error that can be fixed by activating/deactivating libs, or is it something more serious?
