Same here

I only get a grey screen and the systems returns to the launcher.
Games work, but starting Amibench or applications that rely on it (Final Writer, DOpus etc.) crash.
It seems like altering things on Amibench (like font sizes e.g.) make the system fail at the (next) start.
Until today I was able to restore the system to the inbuilt defaults, but that does not help now (I clicked it several times after a reboot, fresh start and with different combinatios of volumes / partitions to restore).
Any advice on how to cure this?
