Scilab hangs after modules installation

Hi @ all,
installed Scilab 5.5.0 without problems. After Installation of some modules with Atoms Scilab does't start completely anymore. It hangs trying to load Xcos toolbox skeleton. I cannot start Atoms to uninstall Xcos toolbox skeleton. No Scilab console commands can be performed.

Does anybody know how to uninstall this skeleton? Or have somebody other Ideas to get Scilab running? How to uninstall Scilab completely (with its modules)? Tried to uninstall it via Yast but the modules are still remaining.


Thanks for Helping!
