I have 55gbs on my ps3 and I barley have anything on it. But it won't let me download any new. And even old demos like metal gear rising. Sly Cooper. And heavenly sword? It says insufficient storage. Please help me.
Are you sure you're reading the capacity properly? How bout a screen shot?
Cognitive Dissonance - The ability to understand multiple viewpoints even if they conflict with one another - and still use critical thinking, logical thought, and common sense to come to the realization that only ONE is the correct one and the others are wrong.
You probably downloaded patches and other stuff without even knowing it. If there isn't anything on your system that you want to keep, I suggest you try erasing the HDD (through system settings) and you will get more space to download demos.
You probably should consider getting a 50GB HDD in the future, at this point you should easily find one for under $50 online. PSN downloads are just getting bigger, and you will keep running into this issue if you don't change your HDD....
