Ximian and 7.3

Hello, I have SuSE 7.3 installed, using KDE and Gnome, with KDE as default in startx. Today I've installed Ximian by their site. Installed OK. The problem is that Gnome desapeared, and I can't run Xinian. Gnome desapeared from susewm also. Do someone has an idea about the problem ??? Thanks, Parra
