PS vita problem

So i got a vita to replace my now old psp. I transferred some save data from the psp to the vita just fine. The problem is that a save data failed to load. From example; through the vita I re-downloaded DJ max portable 3, once I started the game failed to load my psp version of my save file, stating "it was from another psp" and prompt to start a new file erasing the old one. Is there a way to solve this?

Since my vita doesn't have any transfered save data... try this.

That's exactly what I did. I re-did the process and I still got the same thing;
"Load failed. This save data was created by another PSP system. Do you want to start this game?(If you continue, previous save data will be lost)
