I'm having these issues:
When I try to download something I've already downloaded, it either
a) starts downloading but says "Can't download" immediately
b) downloads up to completion but in the end it says "Can't download"
c) downloads successfully, but when I check in Memory, it ends up being "Incomplete data"
d) shows the "Confirm Download" screen, as if I have never downloaded the file before instead of the "You have downloaded this. Would you like to re-download again?" with the Download Again option below.
Can anyone please help me? Before you ask, my only option is to delete the files, otherwise I'd have the urge to restore my files and I don't have enough storage to back up my files instead of deleting them (I have 25GB of Rock Band DLC and that's not all!)
I've cleared the cache, opened up my ports on my router (tried with ports and no ports opened), rebooted my router and even used a wired connection and a wireless, alternating.
Also, I've managed to download some files of small file sizes. And I also have 17 pages of download history, with almost half of them I won't considering re-downloading again (redundant gamerpics, themes, outdated files, etc)
