ok Lok - last time I'm showing you how nice I'm. I'll describing escpecially for you what i did step by step.
1. I delated everything what was connected with sonicstage software, everything what contained "mg", "sony", "real", "jukebox", etc. by add/remove and manually
2.then I checked what updates (from microsoft) for windows (I use XP) are available - there was "service pack 3" or something like this. It was like 100 MB - I downloaded it.
3. restart your PC - enjoy fuckin' sonicstage - it works again - I've got 1.5 version and I didn't have to download newer version
that's the whole secret - I didn't have to delate anything else
after this my internet explorer fucked up..never mind..
