first, i had already said this a lot of times, but will say it for the sake of this forum. You need a UMD to be loaded. Meaning any UMD will do. You can just buy a Demo UMD from game shops or Sony Gallery. It should not cost more than $10[that was the price i bought it for]. Or you can even buy a game to load it in[not recommended, cos you can play downloaded games why you spend so much?]. The UMD is just to "bluff" the PSP that you are running the game from the UMD and not the Memory stick[the place your downloaded games is saved to]. So it does not matter what UMDs you buy. As long as its a UMD, just load it into the PSP and you should have to problem loading it. If loaded the UMD inside already still can't, i suggest you just slam your PSP on the floor and step hard on it. Or, go back to the shop which you bought the PSP and ask for advice. OR, check the version of your PSP. Check if your PSP is downgraded and able to play downloaded games anot first before making more noise. If its not, then check here to find your PSP version.
