Errcode=-4 with some games

Could anyone please tell me what I need to do to stop getting[Rom loading failed] load rom errcode=-4message when I download some games on to my daughter's DSTT card? eg Moshi Monsters - Moshling Zoo. However Pinball deluxe works without a hitch. Does the message just mean I need to accept that some games will nt work or is there anything I can do to rectify the problem?Grateful,Denr

you need to update your DSTT card files, if that doesnt works, make a backup of the contents of the microsd card and format it using the panasonic formatter.
