install failed 80109b82

i get the above error message whenever i try to install games i've downloaded from PSN onto my PSP

anybody know the cause / solution?:(

And, check to make sure you are downloading the titles to a PSP which is registered and activated for the account you purchased them with... I see a TON of people posting about account confusions because they have more than one.

Also, if you also have a PS3, I've found it's easier and faster to download directly to the PS3 and then transfer over to the PSP. You might try that.
