gamediscs stopped working

Hi, i'm a longtime wiibrew-visitor but i'm new on this forum. So i don't know if this is the right place to put this question.

Since a couple of days I'm unable to play my slightly older gamediscs. I did some googleing and found out these gamediscs are running on IOS21. But somehow i get the wii menuscreen when i start these discs.

Until now i've installed:
- homebrew channel
- dvdx
- Wii Shop and IOS51 installer
- and a system update from the madworld disc (heard no warnings about this)
I'm still working in 3.4 i think

Any help?

The problem disappeared :S

After using libwiigameload which started the discs perfectly in IOS36, the system menu also starts my games again.

Still strange though..
