Yea i tried it right now. I installed Actraiser from an nsp yesterday. After the sys-patch update it didn't start.
Then i deleted it and reinstalled it. From the same nsp it works :)
I tried a hakete 6.4.1 that was released for about 30 mins but still when i start the game the error comes again.
Do i have to config something when using sys-patch over ultrahand?
