I have around 5-6 PSN games that used to work while I was on 3.41, and now only 1 of them still works. The rest all give me an error 80029519. Is this because they were possibly patched to run on 3.41 and not 3.55 ?

Is there a way to get these working on 3.55 or will I have to wait for versions of them which have been patched to work on 3.55 ?
