I'd read those hits.
I am using the PlayStation store downloaded that transfers stuff from the online store to the PSP. I recently downloaded a game demo and a theme and that worked perfectly. Then everything else I tried to download after that crashed the program. It gives me the window that says: (psndl.exe is the downloaded)
psndl.exe has encountered a problem and needs to close.
This error appears every time I try to download something from the PlayStation store.
