PSP Go Rewards program hitting DRM-laced brick wall

Needless to say, none of this applies to the Americans in attendance, but for international PSP Go buyers looking forward to taking advantage of Sony's PSP Go Rewards program, the always user-friendly DRM seems to be putting a solid kink in those enjoyment plans. According to a growing number of users at the official European PlayStation boards, an error by the name of 80109D53 is causing downloaded titles to not play back on the new handhelds. We're told that Sony is aware of the issue and is toiling away in an effort to fix things, but for now, it seems as if you can sidestep some of the risk by downloading your trio of free titles (which Sony offers if you're an existing UMD owner) directly to the PSP Go rather than sideloading 'em from a PS3. Any others having this issue? Figured out a solution? Shoot your mouth off in comments below.
