[PS3] Cannot install demos?

[Insanecyclone]

Great thing about the PS3 is that not only does it look nice but not being able to play a demo is even greater. But no seriously this is getting annoying I've been wanting to try most of the ps3 demos on here and I keep getting an error message every time I try to install it to play it. Some demos have installed like Fracture, Killzone 2, Valkyria Chronicles worked for me but others that I've wanted to try like the Ratchet and clank demo and the wolverine game will not install. Should I delete and re-download a demo if it has this problem again?

What was the error? Only time I had a problem was when a download corrupted itself during a background download, to which I had to redownload the whole damn thing again.

Try deleting the problem demos you owere getting then redownload them without using the Download in Background feature

I just had this problem the other day when I upgraded the HDD. I had to re-download my stuff and one of the downloads had a problem installing with the same error posted. I just had to re-download again and it was fixed. It was probably just a corrupt file or something.
