I'm with the other poster too, you're whining and if you can't find more than 5 games worth buying on a PS3 you got the worlds weirdest tastes or you have little concept of a 'fun game.'
I have no idea why you're going the hard way around placing that game on your PSP really I don't. Sure you can use Media Go, and I'm going to guess you have no access to WiFi because you can download straight onto the PSP which is fast and easy. I'm also going to guess that you don't keep your PC files up to date if you're blaming your issues with flash on the Sony experience too so you get no sympathy there either.
Not too much offense but as I've seen you on here for years but you're the biggest fucking crybaby if you think all that stuff really.
The easiest way is the plug the PSP into a wifi hotspot area whereever, login/pass to PSN and then enter code and download. If that fails, then you can download the game from Sony onto your PC, then go into Explorer and then drag/drop the game from the PC directory to the games directory on the PSP memory card. Or you can go the slowest most steps involved way about it using media go which I avoid. Media Go if you go that route is required because of the encryption routine as they want to reg your PSP to the Media Go program to ensure you're not pirating it which is no biggie. I've converted movies and audio and jammed them into the PSP using the program, it's simple.
Blame yourself really as it's setup for anyone to not have these kind of problems.
